The Importance of Open Source Digital Wallets to the Future of the Internet

On September 13, the Linux Foundation (LF) announced its intent to form the Open Wallet Foundation (OWF) at its Open Source Summit Europe in Dublin. The OWF aims to develop open source software, key building blocks, and best practices that anyone can use as a starting point to build multi-platform, highly secure, privacy-protecting digital wallets. In addition, the OWF will advocate for the wide adoption of open source wallets that can be used to support a wide variety of applications, from payments to digital identities.

The LF was originally founded in 2000 as the Open Source Development Labs to help set the standards for the Linux operating system and support its continued development and commercial adoption. It grew over the years and assumed its current name, Linux Foundation, in 2007. Over the past decade, the LF has undergone a major expansion beyond its original Linux mission. It now has over 1,260 company members and supports hundreds of open source projects. Some of the projects are focused on technology horizontals, - e.g., AI, blockchain, security, cloud, - and others on industry verticals, including energy, automative, government, and health care.

Let me attempt to explain the importance of this announcement by addressing three key questions: what is a digital wallet?; what are digital identities?; and why do we need standard-based, open source digital wallets?

The 2022 State of AI in the Enterprise

“Rapidly transforming, but not fully transformed - this is our overarching conclusion on the market, based on the fourth edition of our State of AI in the Enterprise global survey,” said Becoming an AI-fueled organization, the fourth survey conducted by Deloitte since 2017 to assess the adoption of AI across enterprises. “Very few organizations can claim to be completely AI-fueled, but a significant and growing percentage are starting to display the behaviors that can get them there.”

AI is increasingly viewed by workers as a trusted assistant. “Within just the last 18 months, AI capabilities have advanced considerably, maturing from what was often experienced as a bothersome critic - telling workers what to do or pointing out their mistakes - to more frequently serving as a copilot, independently executing on insights and trends surfaced through the power and speed of cloud- based data hosting and computation.”

These conclusions are similar to those of Stanford’s 2022 AI Index report, which found that AI was becoming more affordable and higher performing, with lower training costs and faster training times across a number of AI tasks including recommendation engines, image classification, object detection, and language processing. This has led to the widespread commercial adoption and increased real-world impact of AI systems.

The Carnegie Cloud Governance Project

Two years ago, the Carnegie Endowment launched the Cloud Governance Project, a multi-year study on the governance challenges associated with cloud computing. “This project recognizes that the cloud offers huge benefits for individuals, organizations, and national economies through greater IT convenience, flexibility, and cost savings,” said the project’s website. “However, the risks of a major disruption affecting cloud services will invite regulation by governments at the local, national, and international levels. Moreover, as the world grows increasingly dependent on the cloud, other aspects of the technology – related to consumer protection, sustainability, inclusiveness, and human rights – will also attract scrutiny and regulation to protect or advance public interests.”

I’ve been closely following cloud computing since it first emerged in the late 2000s. In 2008 I gave a talk at a conference on The Promise and Reality of Cloud Computing. Most everyone at the conference agreed that something profound and exciting was going on, but there was no real consensus on what cloud computing was. A major reasons for both the excitement and lack of consensus about cloud is that we were basically seeing the emergence of a new model of computing in the IT world, only the third such model in the history of computing. The mainframe-based centralized computing model first appeared in the 1960s. Then came the PC-based client-server model in the 1980s. The more recent internet-based cloud computing model emerged in the late 2000s.

Over the past fifteen years, cloud has gone through three major stages. First came infrastructure-as-a-service, offering near unlimited scalability at very attractive prices. Then came software-as-a-service, offering a faster and less costly way of prototyping and deploying innovative applications leveraging advanced tools like containers, Kubernetes, and microservices. Cloud computing has now become a major engine of business transformation, helping companies adapt to the accelerated digitalization of the economy, especially since the advent of Covid-19 in March of 2020.

A Framework for Understanding the Power of Platforms

This past July, MIT’s Initiative on the Digital Economy held its 10th annual Platform Strategy Summit. The hybrid Summit included a number of panels and keynotes throughout the day, a few of which I attended online. In particular, I’d like to discuss the very interesting presentation by Boston University professor Marshall Van Allstyne as part of a panel on emerging trends in which he raised and answered five fundamental questions about platforms:

• Structure: Why do platforms have such high market caps but so few assets or employees?
• Strategy: Why does traditional product strategy fail in platform markets?
• Regulation: Why does traditional antitrust fail in platform markets?
• Fake News: Why is misinformation such a hard problem?
• Can Decentralized Autonomous Organizations dethrone platforms?

In his presentation, Van Alstyne, aimed to articulate a single framework that will help answer all five questions, that is, a consistent way of thinking about platforms based on the research that he and his colleagues have been conducting over the past decade. Let me summarize Van Alstyne’s presentation by first describing his unifying framework, followed by how the framework applies to each of the five key questions.

Web3: The Promise of a Blockchain-Based Internet of Value

On June 30, MIT hosted the Imagination in Action Web3 Summit, an event jointly organized by MIT Connection Science, Forbes, and Link Ventures. The Summit brought together almost 600 developers, entrepreneurs, investors, and academics to discuss the present state and potential evolution of Web3. The agenda featured a number of panels and talks. Speakers included Alex (Sandy) Pentland, - MIT professor and Connection Science Director, Michael Federle, - CEO of Forbes, John Werner, - Managing Director at Link Ventures, and Esther Dyson, - investor, journalist, and philanthropist.

The MIT Summit is the first in a series of Imagination in Action conferences. The next one will take place on October 6 in San Francisco, followed by one on January 17 at Davos, and back to MIT in June of 2023. The summits aim “to take us from reflections on the last major social and economic transformation precipitated by the arrival of the Internet era, to the economics to build and the governance to sustain Web3,” as well as to envision the possibilities of a Web3 future and to try to discern hype from reality in these early days of a potential new internet era.

I wasn’t able to attend the Summit in person, but I watched the recordings of a number of the sessions, where I heard a variety of opinions on what Web3 is about. This is not surprising. In their early years, major new technologies are generally accompanied by a mixture of excitement, speculation and confusion, as people sort out what the technology might be about and how it’s likely to evolve. Something important is going on out there, but it takes time and marketplace experience to sort things out.

I’ve seen this play out a few times throughout my long career in the IT industry, especially in the early 1990s as the internet was transitioning from a DARPA-sponsored project in the research community to an initiative that was starting to take the broader marketplace by storm. A lot was happening around the internet, but it wasn’t at all clear where things were heading, and in particular what the implications would be to the world of business. Let me share some of the lessons learned in the 1990s while formulating IBM’s internet strategy in our newly formed Internet Division.

The Economic Potential of the Internet of Things

In June of 2015, the McKinsey Global Institute published a report on the Internet of Things (IoT). The report analyzed the long term economic potential of IoT by examining over one hundred use cases and the IoT-based solutions in which they were generally deployed such as factories, homes, offices, and cities. It then estimated that the economic potential of IoT by 2025 would be approximately $3.9 trillion to $11.1 trillion per year.

The estimate was based on the likely evolution of technology and the rate of adoption of IoT solutions between 2015 and 2025, as well as economic and demographic trends. The estimated range was so wide because there were so many unknowns at that early stage in IoT’s development, including the costs of technology, the rate of development and deployment of these highly complex solutions, their level of acceptance by consumers and workers, and the policies and regulations enacted by governments.

Six years later McKinsey published a new report, The Internet of Things: Catching up to an accelerating opportunity, which updated the 2015 analysis. The recent report evaluated how much of its projected value in the earlier report had been captured and estimated the IoT’s economic potential through 2030, as well as the key headwinds slowing its progress and the key tailwinds propelling it forward.

“While the potential economic value from the IoT is large and growing, capturing this value has proved challenging,” said the recent report. “Our latest research shows that the total value captured in 2020 ($1.6 trillion) is at the lower end of the range of the scenarios we mapped out in 2015. We have updated our estimates for 2025 and beyond by adjusting for current conditions, and we have developed scenarios that account for the range of various uncertainties. In aggregate, both the low- and high-end scenarios are lower than the original 2015 estimates: around $2.8 trillion to $6.3 trillion in potential IoT economic value in 2025, compared with around $3.9 trillion to $11.1 trillion from the 2015 work.”

The Powerful Human Forces Driving the End of Globalization

“I can remember a time  - about a quarter-century ago - when the world seemed to be coming together,” wrote NY Times columnist David Brooks in a recent essay, Globalization Is Over. The Global Culture Wars Have Begun. “The great Cold War contest between communism and capitalism appeared to be over. Democracy was still spreading. Nations were becoming more economically interdependent. The internet seemed ready to foster worldwide communications. It seemed as if there would be a global convergence around a set of universal values - freedom, equality, personal dignity, pluralism, human rights.”

“We called this process of convergence globalization,” he added. “It was, first of all, an economic and a technological process - about growing trade and investment between nations and the spread of technologies that put, say, Wikipedia instantly at our fingertips.”

The 1990s ushered a golden age of globalization, when the world seemed indeed to be coming together. Thomas Friedman’s The World is Flat became an international best-seller in 2005 by nicely explaining what globalization was all about, including the key forces that contributed to flattening the world, - from the collapse of the Berlin Wall in November of 1989 and the Netscape IPO in August of 1995, to the rise of outsourcing, offshoring and global supply chains.

But, ever since the 2008 global financial crisis, globalization and global trade started to slow down. “Globalisation has slowed from light speed to a snail’s pace in the past decade for several reasons,” wrote The Economist in a 2019 article. “The cost of moving goods has stopped falling. Multinational firms have found that global sprawl burns money and that local rivals often eat them alive. Activity is shifting towards services, which are harder to sell across borders: scissors can be exported in 20ft-containers, hair stylists cannot.”

The Open Source AI and Data Ecosystem

“The availability of enterprise-grade open source software (OSS) is changing how organizations develop, maintain, and deliver products,” wrote Ibrahim Haddad in a recent report, Artificial Intelligence and Data in Open Source. Haddad is VP of Strategic Programs at the Linux Foundation (LF) and Executive Director of the LF AI & Data initiative. “Using and adopting OSS can offer many benefits, including reduced development costs, faster product development, higher code quality standards, and more. The open source methodology offers key and unique benefits to the domains of AI and data, specifically in areas of fairness, robustness, explainability, lineage, availability of data, and governance.”

Earlier this year, Stanford released the 2022 AI Index report, its fifth annual study on the impact and progress of AI. The Stanford report noted that “2021 was the year that AI went from an emerging technology to a mature technology - we’re no longer dealing with a speculative part of scientific research, but instead something that has real-world impact, both positive and negative.” 

A few weeks ago I wrote about the impressive scope of the Linux Foundation. The LF supports a large and growing number of open source projects in a wide variety of areas. AI is no different from other technology domains, so it’s not surprising that open source now plays a major role as AI is being increasingly integrated into the economy.

Disruptive Forces Necessitate Bold Decisions

In January of 2021 I attended Predictions 21, an online event organized by Forrester Research.  “Faced with the pandemic, firms did things that once seemed impossible - sometimes overnight,” said Forrester last year, adding that “2021 will be the year that every company - not just the 15% of firms that were already digitally savvy - doubles down on technology-fueled experiences, operations, products, and ecosystems.”

Earlier this year I attended Predictions 22, and was particularly curious to see how things had changed in the intervening year. “Disruptive Forces Necessitate Bold Decisions,” was the overriding message in this year’s event guide.  “The old ways of working no longer work. The future is up for grabs. Leading firms will use the crucibles of 2020 and 2021 to forge a path to an agile, creative, and resilient tomorrow.”

Let me summarize some of Forrester’s key predictions in three areas: technology, customer experience, and industry trends.

The 2001 Hispanic Engineer of the Year Award

In 2001, I had the honor of being named Hispanic Engineer of the Year by Great Minds in Stem (GMiS), - one of the proudest moments in my career. GMiS is an organization dedicated to ensuring that Hispanic students of all ages are inspired to pursue careers in Science, Technology, Engineering and Math (STEM). For 33 years, GMiS has recognized the achievements of the top engineers and scientists in the US Hispanic community that have been nominated in more than 20 categories in industry, government, academia and the military. Winners receive their awards at a gala event that serves as the climax of the annual GMiS conference.

A few weeks ago I received an email announcing that the 2022 GMIS conference will take place in October in Pasadena. A few days later a childhood friend sent me an article about the great Afro-Cuban singer Celia Cruz, whose music I’ve been listening to since growing up in Havana and who like me left Cuba in 1960. It reminded me that when we were asked to pick the walk-in music we wanted played as we approached the podium to receive our award and give our acceptance speech, I picked a song by Celia Cruz. Finally, earlier this year I signed up to 23andMe which confirmed that my DNA is 99.7% Ashkenazi Jewish, not surprising given my parents background.

I went back and looked at the speech I gave over 20 years ago. I hadn’t look at those remarks in a long time, but as I read them, the words still resonated with me, particularly because they reflect my multi-cultural Jewish-Cuban-American heritage. Let me share what I said back then.

Web3 - Safeguarding Our Identity and Personal Data in the Digital World

Transformative technologies are generally accompanied by a mixture of excitement and confusion in their early years. Something important is going on out there, although there’s no consensus on what it is yet. A major reason for the lack of consensus is that there’s no single dimension around which to define an emerging technology or business model. It’s like the fable of the blind men and the elephant. Each one touches a different part of the elephant. They then compare notes on what they felt, and learn that they are in complete disagreement.

This was the case with the advent of the commercial internet in the early 1990s. A lot was starting to happen around the internet, but we weren’t sure where things were heading. It was pretty clear that a communications revolution was underway: after all, the internet was fundamentally a network of networks, and email was one of its earliest and most popular applications. It was also an information revolution: anyone with a browser, a PC, and an internet connection could now access all kinds of content in the new World Wide Web. And, above all, it promised to be an economic revolution: the internet ushered a historical transition to a new kind of digital economy, including many innovative e-business applications.

Over the past few decades, the term internet has come to encompass a number of related technologies including broadband networks, mobile devices, social media, cloud computing, e-commerce platforms, big data, AI, and more. More recently, we’ve seen the emergence of a new set of technologies and business models that are once more generating excitement, confusion, and multiple opinions on what they’re all about: Web3.

Last week I wrote about web3, referencing two recent books: the just-published Digital Asset Revolution by Alex Tapscott, and the soon-to-be-published Think Blockchain by Jerry Cuomo.

I wrote that web3 aims to usher a more open, entrepreneurial internet and digital economy by replacing today’s corporate mega-platforms with blockchain-based decentralized networks. Web3 would thus give creators, developers and users a way to monetize their contributions, involve them in the governance and decision-making of the platforms supporting their work, and give individuals more privacy and control over their data.

I now want to discuss another perspective on web3 based on The Emerging New Economy: Causes and Consequences of Web 3.0, a recent Stanford seminar by Alex (Sandy) Pentland, MIT professor and faculty director of the MIT Connection Science Research initiative, - with which I’ve long been affiliated as a Connection Science Fellow.

The Potential Impact of Web3 on the Internet and the Digital Economy

A few weeks ago, the Blockchain Research Institute (BRI) announced that its annual global conference would be renamed Web3 Blockchain World, and that the Enterprise Blockchain Awards would now be called the Web3 & Blockchain Transformation Awards.

I’ve been affiliated with BRI for a number of years as a research contributor and as chair of its blockchain awards committee. I was somewhat concerned with the name change, because, as is generally true of new technologies in their early stages, there are multiple views of what web3 is all about. Critics view web3 as little more than hype, a rebranding effort to shed some of the cultural and political baggage of crypto, while supporters believe that web3 represents the future of the internet, upending traditional gatekeepers and ushering a middleman-free digital economy.

Over the following weeks I learned from BRI founder Don Tapscott his reasoning behind the decision that BRI should embrace web3 in its research and events. I read Think Blockchain, a book by IBM Fellow and VP of Blockchain Technologies Jerry Cuomo that will be published later this month. I read the section on Web3 and the New Internet of Value in Digital Asset Revolution, a book by BRI co-founder Alex Tapscott that was just published earlier this week. And I looked at a number of articles from both supporters and critics of web3.

In the end, I became convinced that web3 is now where the commercial internet was in the early 1990s, cloud computing in the late 2000s, and blockchain in the mid 2010s: a very promising set of technologies and applications in their early years. While, at this stage it’s not yet clear how it will evolve, it’s time to start paying serious attention to web3 and try to influence its directions. Let me briefly share my views of web3.

Foundation Models: AI’s Exciting New Frontier

Over the past decade, powerful AI systems have matched or surpassed human levels of performance in a number of specific tasks such as image and speech recognition, skin cancer classification and breast cancer detection, and highly complex games like Go. These AI breakthroughs have been based on deep learning (DL), a technique loosely based on the network structure of neurons in the human brain that now dominates the field. DL systems acquire knowledge by being trained with millions to billions of texts, images and other data instead of being explicitly programmed.

These task-specific, DL systems have generally relied on supervised learning, a training method where the data must be carefully labelled, - e.g., cat, not-cat, - thus requiring a big investment of time and money to produce a model that’s narrowly focused on a specific task and can’t be easily repurposed. The rising costs for training ever-larger, narrowly focused DL systems have prompted concerns that the technique was running out of steam.

Foundation models promise to get around these DL concerns by bringing to the world of AI the reusability and extensibility that have been so successful in IT software systems, from operating system like iOS and Android to the growing number and varieties of internet-based platforms.

The Impressive Scope of the Linux Foundation in the 21st Century Digital Economy

Last week, the Linux Foundation held its North America Open Source Summit in Austin. The week-long summit included a large number of breakout sessions as well as several keynotes. Open Source Summit Europe will take place in Dublin in September and Open Source Summit Japan in Yokohama in December.

I’ve been closely involved with open, collaborative innovation and open source communities since the 1990s. In particular, I was asked to lead a new Linux initiative that IBM launched in January of 2000 to embrace Linux across all the company’s products and services.

At the time, Linux had already been embraced by the research, internet, and supercomputing communities, but many in the commercial marketplace were perplexed by IBM’s decision. Over the next few years, we spent quite a bit of effort explaining to the business community why we were supporting Linux, which included a number of Linux commercials like this one with Muhammad Ali that ran in the 2006 Super Bowl. IBM also had to fight off a multi-billion dollar lawsuit for alleged intellectual property violations in its contributions to the development of Linux. Nevertheless, by the late 2000s, Linux had crossed the chasm to mainstream adoption, having been embraced by a large number of companies around the world.

In 2000, IBM, along with HP, Intel, and several other companies formed a consortium to support the continued development of Linux, and founded a new non-profit organization, the Open Source Development Labs (OSDL). In 2007, OSDL merged with the Free Standards Group (FSG) and became the Linux Foundation (LF). In 2011, the LF marked the 20th anniversary of Linux at its annual LinuxCon North America conference. I had the privilege of giving one of the keynotes at the conference in Vancouver, where I recounted my personal involvement with Linux and open source.

How to Build Organizational Resilience to Cyberattacks

I became quite interested in cybersecurity around a year ago, given the growing threats of cyberattacks by criminal groups and adversarial governments. I then joined CAMS, MIT’s interdisciplinary cybersecurity consortium and started attending its online weekly seminars. A few weeks ago I attended a CAMS seminar on cyber resilience by Manuel Hepfer, a research affiliate at Oxford University and a research analyst at ISTARI, a cyber risk management company.

What is cyber resilience? While cybersecurity is the practice of protecting critical systems and sensitive information from digital attacks, cyber resilience is the ability to prepare for, withstand, and recover rapidly from any major disruption, whether an intentional cyberattack or a natural disaster.

The seminar was based on a study by Hepfer and colleagues of the 2017 NotPetya ransomware attacks, a series of powerful cyberattacks which caused over $10 billion in global economic damage across a number of industries. Their study was primarily focused on three global companies that were the subject of NotPetya attacks: a logistics company with over 60,000 employees, a manufacturing one with over 20,000 employees, and a third in professional services with over 5,000 employees.

The study conducted around 50 interviews with senior executives across the three companies, including CEOs, CFOs, CIOs, and CISOs. In addition, it reviewed internal documents, presentations, press releases, newspaper coverage, and audio and video files related to events before, during, and after the attack. Their study was published in two articles in the MIT Sloan Management Review, the first in 2020, the second in 2022.

Can We Trust Our Impressive AI Language Models?

One of the key findings of the 2022 AI Index Report was that large language models (LLMs) are setting records on technical benchmarks thanks to advances in deep neural networks and computational power that allows them to be trained using huge amounts of data. LLMs are now surpassing human baselines in a number of complex language tasks, including English language understanding, text summarization, natural language inference, and machine translation.

A.I. Is Mastering Language. Should We Trust What It Says?, a recent NY Times Magazine article by science writer Steven Johnson, took a close look at one such LLM, the Generative Pre-Trained Transformer 3, generally referred to as GPT-3. GPT-3 was created by the AI research company OpenAI. It’s been trained with over 700 gigabytes of data from across the web, along with a large collection of text from digitized books. “Since GPT-3’s release, the internet has been awash with examples of the software’s eerie facility with language - along with its blind spots and foibles and other more sinister tendencies,” said Johnson.

“So far, the experiments with large language models have been mostly that: experiments probing the model for signs of true intelligence, exploring its creative uses, exposing its biases. But the ultimate commercial potential is enormous. If the existing trajectory continues, software like GPT-3 could revolutionize how we search for information in the next few years.” Instead of typing a few keywords into Google and getting back a long list of links that might have the answer, you’d ask GPT-3 what you’re looking for in English and get back a well-written, accurate answer. “Customer service could be utterly transformed: Any company with a product that currently requires a human tech-support team might be able to train an L.L.M. to replace them.”

A Human-Compatible Safe, Controllable AI

“Even in its present state, the technology of artificial intelligence raises many concerns as it transitions from research into widespread use,” wrote UC Berkeley professor Stuart Russell in a recent essay, If We Succeed. “These concerns include potential misuses such as cybercrime, surveillance, disinformation, and political manipulation; the exacerbation of inequality and of many forms of bias in society; the creation and deployment of lethal autonomous weapons; and the usurpation of human roles in the economy and in social relationships.”

“My concern here, however, is with the potential consequences of success in creating general-purpose AI: that is, systems capable of quickly learning to perform at a high level in any task environment where humans (or collections of humans) can perform well.” Decades ago, Alan Turing expressed a similar concern. While answering a question during a lecture in 1951, Turing said: “It seems probable that once the machine thinking method had started, it would not take long to outstrip our feeble powers. … At some stage therefore we should have to expect the machines to take control.” Over the past decade, a number of public figures like Stephen Hawking and Nick Bostrom have argued that a superintelligent AI could become difficult or impossible for humans to control, and might even pose an existential threat to humanity.

Until recently, we didn’t have to worry about the consequences of such superhuman AIs because AI applications weren’t all that smart and were mostly confined to research labs. But, powerful AI systems have now matched or surpassed human levels of performance in a number of application- specific tasks such as image and speech recognition, skin cancer classification, breast cancer detection, and complex games like Jeopardy and Go. While these application-specific breakthroughs, - generally referred to as soft, or narrow AI, - were once viewed as the exclusive domain of humans, AI still lacks the deeper, general-purpose human intelligence that’s long been measured in IQ tests.

The MIT Digital Insider Podcast with Sinan Aral

Earlier this week, MIT’s Initiative on the Digital Economy launched a new podcast, The Digital Insider with Sinan Aral. Aral is Professor in the MIT Sloan School of Management and Director of the Initiative on the Digital Economy, where I’ve been a Fellow since it was founded in 2012. He’s the author of the 2020 book The Hype Machine.

I like to take a walk every day, weather permitting, and one of the reasons I enjoy my walks is the opportunity to listen to a podcast. I just listened to the first episode of The Digital Insider. It was truly excellent.

In the episode, Sinan interviewed Maria Ressa, a Filipino-American journalist and author, and co-founder and CEO of Rappler, a Philippine online new website. Maria has been a prominent critic of the human right abuses of Philippine President Rodrigo Duterte, for which she’s been arrested and convicted. Along with Russian journalist Dmitry Muratov, Maria was awarded the 2021 Nobel Peace Prize for “their efforts to safeguard freedom of expression, which is a precondition for democracy and lasting peace.”

The Digital Insider podcast aims to explore the hard science behind the digital economy as well as how the digital economy actually works. “From AI bias to NFTs; fake news to two-sided markets; cryptocurrencies to quantum computing, Sinan and guests make sense of the lightning-fast changes taking place in the tech driven world.”

I highly recommend it.

The Digital Divide in How We Use the Internet

A few weeks ago I attended an MIT seminar by Esteban Moro, professor at Universidad Carlos III in Madrid and visiting professor at MIT. Moro’s talk discussed the socio-economic digital divide based on how we use the internet, focused on two key questions: how profound is the digital usage gap in our society?; and can we use mobile phone traffic to infer socioeconomic status? His seminar was based on a recently published article in the Journal of the Royal Society Interface co-authored with four collaborators, - News or social media? Socio-economic divide of mobile service consumption.

“Inequality is a central societal problem, especially within rapidly expanding urban areas,” wrote the authors. “While it is a crucial driver for economic growth, the progressive clusterization of workers, industries, companies and services in cities has a tremendous cost in terms of segregation and discrimination. This cost is not only economic: in the same city, different areas can have a 10- to 15-year imbalance in life expectancy and highly divergent education levels, with little chances of social mobility.”

“The design and successful implementation of policies to alleviate these problems require fine-grained, frequently updated information about income, education or inequality across metropolitan areas,” they added. “However, most data sources employed today, such as population censuses or surveys, suffer from sparsity in population coverage or infrequent updating, hence they do not allow the swift evolution that urban societies experience nowadays to be followed. Thus, the traditional ways of understanding cities tend to explain what happened 5 years earlier rather than nowcasting or even predicting urban transformations.”

In his seminar, Moro referred to the socio-economic divide based on how we use the internet as the second digital divide, in contrast to the original digital divide which was based on access to the internet.

(I Can’t Keep No) Satisfaction

(I Can’t Get No) Satisfaction, the Rolling Stones’ 1965 megahit, should have more appropriately been titled (I Can’t Keep No) Satisfaction, wrote social scientist and author Arthur C. Brooks in How to Want Less: The secret to satisfaction has nothing to do with achievement, money, or stuff, - a recent essay in The Atlantic. Brooks has been in the faculty of the Harvard Kennedy School for the past two years, after being president of the American Enterprise Institute from 2009 to 2019.

Satisfaction, he explained, “is the greatest paradox of human life. We crave it, we believe we can get it, we glimpse it and maybe even experience it for a brief moment, and then it vanishes. … In fact, our natural state is dissatisfaction, punctuated by brief moments of satisfaction.”

Our human tendency to pursue satisfaction despite its fleeing nature condemns us to continuously live in a so-called hedonic treadmill. We might not like it, “but Mother Nature thinks it’s pretty great. She likes watching you strive to achieve an elusive goal, because strivers get the goods - even if they don’t enjoy them for long. More mates, better mates, better chances of survival for our children - these ancient mandates are responsible for much of the code that runs incessantly in the deep recesses of our brains.”

The 2022 Work Trend Index: How to Get Hybrid Right

“The people returning to the office are not the same as those who left in March 2020,” wrote Jared Spataro, Microsoft Corporate VP for Modern Work, in a recent Harvard Business Review (HBR) article, 5 Key Trends Leaders Need to Understand to Get Hybrid Right. The article summarized the findings of Microsoft’s 2022 Work Trend Index, a report based on various sources of information, including a survey of 31,000 people in 31 countries, labor trends from LinkedIn, and trillions of signals from Microsoft 365 suite of productivity apps.

“The data shows that the past two years left an indelible mark on the psyche of workers, altering their expectations and fundamentally shifting the way work gets done,” said Spataro. “This is a pivotal moment, where leadership matters more than ever. Those who embrace a new mindset and shift cultural norms will best position their people and their business for long-term success. Adapting to the influx of change in this business environment is no easy feat.”

“After many false starts, organizations are finally making the shift into a true hybrid work model. Like every other turning point over the past two years, there’s no shortage of perspectives on what this next phase will look like.” However, there’s no going back to the way work once was. Adapting to the many changes in this business environment is a challenge now facing every leader. To navigate the transition to hybrid work, leaders need to understand five key trends.

How Can You Trust the Predictions of a Large Machine Learning Model?

Artificial intelligence has emerged as the defining technology of our era, as transformative over time as the steam engine, electricity, computers, and the Internet. AI technologies are approaching or surpassing human levels of performance in vision, speech recognition, language translation, and other human domains. Machine learning (ML) advances, like deep learning, have played a central role in AI’s recent achievements, giving computers the ability to be trained by ingesting and analyzing large amounts of data instead of being explicitly programmed.

Deep learning is a powerful statistical technique for classifying patterns using large training data sets and multi-layer AI neural networks. Each artificial neural unit is connected to many other such units, and the links can be statistically strengthened or decreased based on the data used to train the system. But such statistical methods are not equally suitable for all tasks. Tasks that are particularly suitable for machine learning, exhibit several key criteria, such as the availability of large data sets of well-defined input-output pairs for training ML classifiers, - e.g., carefully labeled cat, not-cat pictures for cat recognition classifiers, and english-french document pairs for machine translation algorithms.

The methods behind a machine learning prediction, - subtle adjustments to the numerical weights that interconnect its huge number of artificial neurons, - are very difficult to explain because they’re so different from the methods used by humans. The bigger the training data set, the more accurate the prediction, but the more difficult it will be to provide a detailed, understandable explanation to a human of how the prediction was made.

A few weeks ago I attended an online seminar, - How Can You Trust Machine Learning? by Stanford professor Carlos Guestrin, - on the difficulty of understanding machine learning predictions. Guestrin’s seminar was based on a 2016 article he co-authored with Marco Tulio Ribeiro and Sameer Singh , “Why Should I Trust You?” Explaining the Predictions of Any Classifier.

Beyond GDP: A Framework for Measuring Economic Progress

“What is meant by economic progress, and how should it be measured?,” asked economists Diane Coyle and Leonard Nakamura in a recent paper, Time Use and Household-Centric Measurement of Welfare in the Digital Economy. “The conventional answer is growth in real GDP over time or compared across countries, a monetary measure adjusted for the general rate of increase in prices. However, there is increasing interest in developing an alternative understanding of economic progress, particularly in the context of digitalization of the economy and the consequent significant changes Internet use is bringing about in production and household activity.”

Gross Domestic Product (GDP) became the accepted international measure of economic progress in the 1940s. It was a good measure for an industrial economy dominated by the production of physical goods, but GDP doesn’t reflect important economic activity beyond production, such as income, consumption and quality of life, nor does it capture measures of economic welfare or utility, that is, the extent to which a service or good satisfies an individual’s wants and needs. In addition, GDP doesn’t include the value of the increasing amounts of free information goods now available in the Internet-based digital economy, including email, texts, social media, maps, apps and videos.

In their paper, Coyle and Nakamura propose an alternative approach for measuring economic progress based on how much time people spend on different daily activities - e.g., paid work, household tasks, leisure, and consumption - combined with measures of well-being while engaged in these different activities. “In an economy that is four-fifths services rather than goods, with time to consume therefore inherent in the majority of economic activity, the utility of the different uses of time seems key to understanding economic welfare as well as productivity.”

Beatlemania: Why Are Success and Failure So Unpredictable?

“Why did the Beatles become a worldwide sensation? Why do some cultural products succeed and others fail? Why are some musicians, poets, and novelists, unsuccessful or unknown in their lifetimes, iconic figures decades or generation after their deaths? Why are success and failure so unpredictable?,” these are among the questions explored in Beatlemania, a draft paper by Harvard professor Cass Sunstein that will be published later this year in the inaugural issue of The Journal of Beatles Studies.

“On one view, the simplest and most general explanation is best, and it points to quality, appropriately measured: success is a result of quality, and the Beatles succeeded because of the sheer quality of their music,” wrote Sunstein. “On another view, social influences are critical: timely enthusiasm or timely indifference can make the difference for all, including the Beatles, leading extraordinary books, movies, and songs to fail even if they are indistinguishable in quality from those that succeed.”

In 1961 the Beatles  were an obscure English rock band from Liverpool, with no manager and modest prospects. They tried to release a debut single, Love Me Do, but every record label they approached rejected them and the band came close to splitting. In January of 1962 Brian Epstein became their manager. Epstein had no experience in managing artists, but he liked their music and sense of humor. He eventually persuaded EMI producer George Martin to audition the band in June of 1962, who despite feeling that they were “a rather raw group” with “not very good songs,” agreed to sign them to a recording contract.

How Do Young People See the World Compared to Older Generations?

“There is an emerging narrative about a growing intergenerational divide worldwide,” said a recent international survey conducted by The Changing Childhood Project. “In the media and in popular culture, the young are often portrayed as impatient, militant, outspoken, and even entitled, in contrast to more sober temperaments among older people. The concept of intergenerational tension is not new. What may be new, however, is the speed with which our world is changing – and with it, childhood.”

The Changing Childhood Project is a collaboration between UNICEF, - the UN agency responsible for providing humanitarian and developmental aid to children around the world, - and Gallup, - the analytics company best known for its international opinion polls. Created to explore these intergenerational shifts, the project seeks to answer a few key questions: what is it like growing up today?; how do young people see the world differently?; and, is there an intergenerational gap?

The 2022 AI Index Report: AI’s Emerging Real-World Impact

On March 16, Stanford’s Institute for Human-Centered Artificial Intelligence (HAI) released the 2022 AI Index report, its fifth annual study on the impact and progress of AI. The comprehensive study was led by an interdisciplinary group of experts from across academia and industry, and highlights the rapid rate of technical and marketplace AI advances, as well as the growing ethical and regulatory concerns associated with AI.

“2021 was the year that AI went from an emerging technology to a mature technology - we’re no longer dealing with a speculative part of scientific research, but instead something that has real-world impact, both positive and negative,” said Jack Clark, co-chair of the AI Index. “This year’s AI Index tells us that AI is being integrated into the economy and the effects of it are beginning to go global across research, deployment, and even funding.” Two weeks ago I attended an online HAI seminar where Clark gave this excellent presentation on the AI Index.

The report is organized into five chapters: Technical Performance, AI Ethics, R&D, Economy and Education, and Policy and Governance. Let me summarize the key findings of each chapter.

The Tech Trends that Will Most Reshape Companies Over the Next Decade

“In the next decade, we’ll experience more progress than in the past 100 years combined, as technology reshapes health and materials sciences, energy, transportation, and a wide range of other industries and domains,” notes a recent McKinsey study on the The top trends in tech. “The implications for corporations are broad.”

“These trends may not represent the coolest, most bleeding-edge technologies. But they’re the ones drawing the most venture money, producing the most patent filings, and generating the biggest implications for how and where to compete and the capabilities you need to accelerate performance.”

“Unifying and underlying them all is the combinatorial effect of massively faster computation propelling new convergences between technologies; startling breakthroughs in health and materials sciences; an array of new product and service functionalities; and a strong foundation for the reinvention of companies, markets, industries, and sectors.”

What Is Web3, and Could It Usher a New Economic System?

Bitcoin was introduced in 2008 with the release of Bitcoin: A Peer-to-Peer Electronic Cash System, which explained how to design a decentralized cryptocurrency and digital payment system without the need for central banks or trusted intermediaries. Blockchain, the digital ledger for managing and certifying the validity of bitcoin transactions, was introduced in the same paper.

Over the years blockchain has transcended its original objectives, and has evolved in two major directions. One continues to focus on blockchain as the underlying platform for bitcoin, but it’s also become the platform for the large number of cryptocurrencies, digital tokens, and other cryptoassets that have since been created. The other is focused on the use of blockchain as a trusted distributed data base for private and public sector applications involving multiple institutions, such as supply chains, financial services and healthcare. The cryptocurrency camp is based on public permissionless blockchains, which anyone can join and require some kind of proof-of-work or proof-of-stake systems. The multi-institution camp is based primarily on private permissioned blockchains where participation is restricted to the institutions transacting with each other.

Given my professional interests, I’m particularly interested in the use of blockchains in business and public sector applications for two major reasons. First, I consider blockchain as a major next step in the continuing evolution of the Internet, helping us enhance the security of Internet transactions and data by developing a layer with the standard encrypted services for secure communication, storage and data access. And, longer term, blockchain technologies can significantly improve the efficiency, resilience, and management of complex global applications involving multiple institutions.

But, while I’ve been somewhat skeptical of the crypto camp, a number of intriguing crypto-related topics have recently captured my attention, including Non-Fungible Tokens (NFTs), Decentralized Finance (DeFi), and especially Web3. These various topics were nicely explained by technology columnist Kevin Roose in The Latecomer’s Guide to Crypto, an article in the March 20 SundayBusiness section of the NY Times.

The Widening Gap Between Technological and Institutional Change

A few weeks ago I read The Exponential Age Will Transform Economics Forever, an article in Wired by Azeem Azhar based on his recently published book The Exponential Age. Azhar’s central thesis is that the chasm between what technology allows us to do and what our institutions are prepared to handle has been rapidly widening. New technologies are being invented and scaled at an ever-faster pace. But our institutions, - including our economic systems, political organizations and social norms, - are changing much more slowly. While technological advances follow an exponential curve, institutional adaptation follow a straight, incremental line.

The gap between technological and institutional change is nothing new. Ever since the advent of the Industrial Revolution, there’s been a significant time lag between the emergence of a transformative technology and its ensuing impact on economies and societies. Even after reaching a tipping point of market acceptance, it takes considerable time, - often decades, - for their benefits to be fully realized.

In The Productivity J-Curve, a 2018 NBER paper, Erik Brynjolfsson, Daniel Rock, and Chad Syverson  explained that general purpose, transformative technologies, - such as the steam engine, electricity, and semiconductors, - “are the defining technologies of their times and can radically change the economic environment. They have great potential from the outset, but realizing that potential requires larger intangible and often unmeasured investments and a fundamental rethinking of the organization of production itself.”

The life cycle of historically transformative technologies consists of two district phases, investment and harvesting. Since the technologies are general purpose in nature, they require massive complementary investments, including business process redesign, co-invention of new products and business models, and the re-skilling of the workforce. Moreover, the more transformative the technologies, the longer it takes for them to reach the harvesting phase when they are widely embraced by individuals, companies and industries across the economy.

The Impact of Open Source on the EU Economy

In the 1990s, open source was generally viewed as experimental approach to software development mostly used by research and academic communities on emerging projects like the Internet and Linux. Open source has since evolved to become a well-accepted model of economic production across just about all private- and public-sector communities around the world. But, while widely used, what’s been the economic impact of open source on nations and firms? This question was addressed in a recent study on the impact of open source on the European economy.

“The increasing relevance of Open Source (OS) during the last two decades requires an update of an in-depth analysis of its current role, position and its potential for the European economy,” said the European Commission (EC) in its report on The impact of open source software and hardware on technological independence, competitiveness and innovation in the EU economy.

“Whereas Open Source Software (OSS) has become mainstream across all sectors of the software industry during the past 20 years, Open Source Hardware (OSH) is still in an emerging phase. However, the business ecosystem for OSH is developing.”

The EC conducted a comprehensive analysis of the commercial uses, costs, and benefits of OSS and OSH. “On the basis of this information, the study assesses the potential for the European Union (EU) to achieve its policy goals (including economic growth, greater competitiveness, innovation, and job creation) through the use, promotion and support of OSS and OSH.”

The Rise and Fall of Nation-States

Several weeks ago I attended The End of Nation-States, by technology executive and consultant Tomás Pueyo, - part of the Stanford Digital Economy Lab seminar series. In May of 2021, Pueyo launched Unchartered Territories, a newsletter he describes as aiming to explore the unchartered territories of a fast changing world “to know how we can prepare for them.”

His seminar discussed the role of information technologies in the rise of nation-states throughout history, and how information technologies are likely to lead to the end of nation-states in the coming decades. Let me summarize Pueyo’s key arguments based on his talk and two related newsletters.

The Rise of Nation-States

In Internet and Blockchain Will Kill Nation-States, published in August of 2021, Pueyo explained how the printing press led to the emergence of nation-states in the 16th century.

The feudal system was the basic structure of society between the 9th and 15th centuries in medieval Europe. Feudalism was based on the relationship between a landed-aristocracy, - e.g., kings, dukes, counts, - and the vassals under their protection who vowed them allegiance. Power in the feudal system was hyperlocal and widely distributed across different landowners. Communication was difficult across different localities, since they each generally spoke different dialects or altogether different languages.

The Catholic Church was the biggest power in medieval Europe. The root of its power was the Church's well organized hierarchy of priests, bishops, archbishops, cardinals, and the Pope, all of which were able to communicate with each other far better than everyone else, - aristocrats and vassals alike.

Getting Ready for the 100-Year Life

“In the United States, demographers predict that as many as half of today’s 5-year-olds can expect to live to the age of 100,” said The New Map of Life, a recent report from the Stanford Center on Longevity. The   cross-disciplinary Stanford Center was founded in 2007 to conduct research on the key issues associated with increased longevity, - from cognitive health to physical well-being and financial security, - with the aim to make long lives healthy and rewarding.

While the 100-year life may be here, we’re not ready. “By the middle of this century, this once unattainable milestone may become the norm for newborns, continuing a remarkable trend that saw human life expectancies double between 1900 and 2000, and still rising in this century, despite the grievous toll of the Covid-19 pandemic,” notes the report. “Longevity is one of the greatest achievements in human history, brought about by reductions in infant mortality, advances in sanitation and medicine, public education, and rising standards of living. Yet the change came about so quickly that the social institutions, economic policies, and social norms that evolved when people lived for half as long are no longer up to the task.”

According to the Stanford Center, there’s a clear distinction between aging and longevity. Aging is the biological process of getting older - the accumulation of changes in a human being over time. Longevity is “the measure of long life,” - the ways to enhance the quality of a long life “so that people experience a sense of belonging, purpose, and worth at all ages and stages.”

How Do Digital Infrastructures Increase a Firm’s Value?

“In the information age, the value of a firm rests fundamentally on how it stores, shares and processes information,” wrote Seth Benzell, Jonathan Hersh, and Marshall Van Alstyne in a recent paper, How APIs Create Growth by Inverting the Firm. “Digital infrastructure is therefore central to a firm’s success.”

But, how do digital infrastructures increase a firm’s value? One method is to make more efficient use of the firms internal capital by modularizing, reconfiguring and reusing the firms IT resources. A second method, used in platform businesses, is to leverage external capital by giving access to the firm’s resources to third parties, and capturing a share of the resulting surplus. Both methods require the implementation of Application Programming Interfaces (APIs), whether for only for internal use by the firm’s developers or exposed externally to the firm’s platform partners. Both methods also feature a modular architecture of remixable resources. “Modularity combines the advantages of standardization typically associated with high volume processes together with the advantages of customization typically associated with bespoke processes.”

“An API is a set of routines, protocols, and tools that standardizes building software applications compatible with an associated program or database. APIs fundamentally are code that control access to information. … They govern the type and format of calls or communications that any application can make of another associated program. The answering program is agnostic about the source of the call, yet can require access permission, and the calling program need not know anything about the internal workings of the answering program. … When designing an API, the architect decides how much of the computer system or data to expose to which users. Being accessible on the web, these API endpoints act as a constant conduit to business processes that the firm itself specifies.”

How Does AI Improve Human Decision-Making?

“Artificial Intelligence (AI) is the newest general-purpose technology (GPT),” wrote Sukwoong Choia, Namil Kim, Junsik Kim, and Hyo Kang in a recent paper, How Does AI Improve  Human Decision-Making? Evidence from the AI-Powered Go Program. “One remarkable characteristic of AI is its ability to provide humans with high-quality predictions at relatively low cost and to automate a wide range of predictions. AI has already outperformed human professionals in many domains - including strategic gameplay, medical diagnosis, and new drug development.” 

“Furthermore, as a GPT, the domains where AI outperforms humans are expanding at a fast pace. The rapid development and adoption of AI thus raise an interesting yet pressing question about how AI affects human tasks in these various domains. Studies of AI and human capital, for instance, have examined the performance gap between humans and AI, highlighting AI’s potential for replacing jobs.” However, we should keep in mind that new technologies have been replacing workers and transforming economies for over two centuries. But, over time, these same technologies led to the creation of whole new industries and new jobs, increasing productivity and economic output, raising earnings, and augmenting the demand for labor.

Workers can increase their productivity and performance when assisted in their jobs by AI-based tools. But beyond its assistant role, AI can play a major instructional role by training human professionals to make better decisions. Recent technology advances have significantly improved the quality and reduced the cost of AI-based predictions.

The paper raises a number of important questions about the use of AI to improve human decisions making. Can we show quantitative evidence that AI-based predictions actually improve the quality of human decisions? If so, by what mechanisms are AI-based human decisions improved? And, do the improvements vary between depending on ones attitude toward AI-based decisions?

The Promise & Peril of Human-Like Artificial Intelligence

In his 1950 seminal paper, Computing Machinery and Intelligence, Alan Turing proposed what’s famously known as the Turing test, - a test of a machine’s ability to exhibit intelligent behavior indistinguishable from that of a human. If a human at a keyboard couldn’t tell whether they were interacting with a machine or a human, the machine is considered to have passed the Turing test. “Ever since, creating intelligence that matches human intelligence has implicitly or explicitly been the goal of thousands of researchers, engineers and entrepreneurs,” wrote Erik Brynjolfsson, - Stanford professor and Director of the Stanford Digital Economy Lab, - in a recent article, The Turing Trap: The Promise & Peril of Human-Like Artificial Intelligence.

“The benefits of human-like artificial intelligence (HLAI) include soaring productivity, increased leisure, and perhaps most profoundly, a better understanding of our own minds. But not all types of AI are human-like - in fact, many of the most powerful systems are very different from humans - and an excessive focus on developing and deploying HLAI can lead us into a trap. … On the one hand, it is a path to unprecedented wealth, increased leisure, robust intelligence, and even a better understanding of ourselves. On the other hand, if HLAI leads machines to automate rather than augment human labor, it creates the risk of concentrating wealth and power. And with that concentration comes the peril of being trapped in an equilibrium where those without power have no way to improve their outcomes, a situation I call the Turing Trap.”

Over the past decade, powerful AI systems have matched or surpassed human levels of performance in a number of tasks such as image and speech recognition, applications like skin cancer classification and breast cancer detection, and complex games like Jeopardy and Go. These AI breakthroughs are generally referred to as soft, narrow or specialized AI, inspired by, but not aiming to mimic the human brain. They’ve been generally based on machine learning, that is, on the analysis of vast amounts of information using powerful computers and sophisticated algorithms, whose results exhibit qualities that we associate with human intelligence.

The Work of the Future Is Ours to Invent

The Work of the Future: Building Better Jobs in an Age of Intelligent Machines, by David Autor, David Mindell and Elisabeth Reynolds was published last week. The new book is based on the multiyear MIT Task Force on The Work of the Future that they jointly co-chaired.

The Task Force was commissioned by MIT President Rafael Reif in the spring of 2018 to address one of the most critical questions of the digital economy, - an economy that technology universities like MIT have played a major role in bringing about: as emerging technologies raise aggregate economic output and the wealth of nations, will they also enable people to attain higher living standards, better working conditions, greater economic security, and improved health and longevity? Led by Autor, Mindell and Reynolds, the task force involved over 20 faculty members from 12 departments at MIT as well as more than 20 graduate students. Its final report was released in November of 2020. In addition, the Task Force published a number of working papers and research briefs.

“Amidst a technological ecosystem delivering rising productivity, and an economy generating plenty of jobs (at least until the COVID-19 crisis), we found a labor market in which the fruits are so unequally distributed, so skewed towards the top, that the majority of workers have tasted only a tiny morsel of a vast harvest.” was the Task Force overarching conclusion. But, it argued that with better policies in place, more people could enjoy good careers even as new technologies transform the very nature of work.

Let me summarize the Task Force key findings which the book builds on:

Is It Possible to Establish Norms for Responsible State Behavior in Cyberspace?

In mid-December, the Council on Foreign Relations sponsored a virtual roundtable with Joseph Nye, - former dean of Harvard’s Kennedy School of Government, - to discuss his recent Foreign Affairs article The End of Anarchy?: How to Build a New Digital Order. Professor Nye has long been regarded as one of America’s preeminent strategic thinkers and political scientists. In the 1970s he chaired the National Security Council Group on Nonproliferation of Nuclear Weapons, and over the past decade he’s brought his expertise to the study of conflict and deterrence in cyberspace.

Cybersecurity is an increasingly important aspect of the of US national security strategy, including global trade and the protection of our critical infrastructures. In June of 2021, FBI Director Christopher Wray compared the danger of ransomware attacks on US firms by Russian criminal groups to the September 11 terrorist attacks. And, in a July editorial, the NY times said that ransomware attacks have emerged as “a formidable potential threat to national security,” given “their ability to seriously disrupt economies and to breach strategically critical enterprises or agencies,” urging governments that “It is a war that needs to be fought, and won.”

At an MIT conference in February of 2019, former US Secretary of State Henry Kissinger was asked if we need cybersecurity control agreements with Russia, China and other nations similar to the nuclear arms control agreements that he spent so much time negotiating during the Cold War. Dr. Kissinger replied that for arms control to be effective, the two sides needed to share information and agree to inspections. But such mechanisms are harder to apply in the digital world, because the transparency that was essential for arms control would be very hard to establish for cyber threats. In addition, while controls of physical arms are relatively explicable and negotiable, the variety and speed of cyber attacks make it much harder to develop adequate control agreements.

A Blockchain-based Framework for Safeguarding the Integrity of Real-World Assets

Blockchains first came to light in 2008 as the architecture underpinning bitcoin, the best known and most widely held cryptocurrency. It’s a truly brilliant architecture built on decades-old fundamental research in cryptography, distributed data, game theory and other advanced technologies. The blockchain’s original vision was limited to enabling bitcoin users to transact directly with each other with no need for a financial institution or government agency to certify the validity of the transactions. But, like the Internet and other transformative technologies, blockchain has now transcended its original objectives.

Blockchains are a kind of distributed ledger technologies (DLT), which also include non-blockchain DLTs. Over the past decade, an increasing number of people, including me, consider blockchains and DLTs as major next steps in the evolution of the Internet. In 2016 the World Economic Forum (WEF) named The Blockchain in its annual list of Top Ten Emerging Technologies citing its potential to fundamentally change the way markets and governments work. “Like the Internet, the blockchain is an open, global infrastructure upon which other technologies and applications can be built,” said the WEF. “And like the Internet, it allows people to bypass traditional intermediaries in their dealings with each other, thereby lowering or even eliminating transaction costs.”

The Internet is a general purpose network platform that unlocked huge innovations and economic value by significantly lowering the cost of connections and supporting a large variety of applications. A major reason for its ability to support so many different kinds of applications is that the Internet’s foundations, its TCP-IP layer, has stuck to its basic data-transport mission, i.e., just moving bits around.  It has no idea what the bits mean or what they’re trying to accomplish.

The design decisions that shaped the Internet back in the mid-late 1980s didn’t optimize for security and privacy, or for the ability to authenticate transactions between two or more parties. That’s all the responsibility of the applications running on top of the TCP/IP layer, and they each generally do it their own way, sometimes not at all. Not surprisingly, the lack of standards for security, privacy and transactional integrity have been the biggest challenges facing the Internet in our fast growing digital economy.

What’s the State of Our Digital Technology Revolution?

I first met Carlota Perez in the mid-2000s when she gave a seminar at IBM based on her 2002 bestseller Technological Revolutions and Financial Capital: The Dynamics of Bubbles and Golden Ages. At the time, we had been living through a series of major changes, - the explosive growth of the Internet, the advent of the digital economy, the dot-com bubble, and the bursting of the bubble. In her excellent presentation Perez explained these turbulent times by positioning them within the historical perspective she wrote about in her book.

If you look at the historical big picture, patterns begin to emerge which serve as a good guide for understanding the past and thinking about the future. Since the onset of the Industrial Revolution we’ve had 5 major technological revolutions, each one lasting roughly 40 to 60 years. First was the age of machines, factories and canals starting in 1771. This was followed by the age of steam, railways, iron and coal, starting in 1829; steel, electricity and heavy engineering in 1875; oil, automobiles, and mass production in 1908, and our present information technology and telecommunications (ICT) digital age starting in 1971.

Technology revolutions are engines of growth, ushering new paradigms for innovation, rejuvenating and transforming the economy, and re-shaping social behavior and the institutions of society. To better understand the dynamics of a technology revolution, we should split it into two different periods, each lasting 20 to 30 years.

A New Measurement Framework for the Digital Economy

Several weeks ago I heard a very interesting keynote presentation by Cambridge professor Diane Coyle at the annual workshop of the Stanford Digital Economy Lab, - What Don’t We Know About Measuring the Digital Economy? Professor Coyle is also a research associate of the UK Economics Statistics Centre of Excellence. In 2017 she was a recipient of the Indigo Prize on how to measure economic activity in the digital economy for her essay Making the Future Count, co-authored with Benjamin Mitra-Kahn.

“GDP captures only market transactions at the price of exchange, and not the welfare gains, externalities, environment, distribution of wealth or innovation which occurs in an economy,” wrote the authors. “Hence almost since its creation in the 1940s it has been criticised for its inability to capture economic welfare. Now changes in the economy, being restructured by digital technology and paying the price for unsustainable growth, make the case for a new measurement framework more pressing than ever. GDP was never an ideal measure of economic welfare and its suitability has been decreasing.”

Gross Domestic Product (GDP) became the accepted international measure of economies in the1940s. While being a good measure for the 20th century industrial economy, GDP is a flawed measure for the 21st century economy. It was suitable when the economy was dominated by the production of physical goods, but GDP doesn’t adequately capture the growing share of services and other intangible assets that now characterize advanced economies. Nor does it reflect important economic activity beyond production, such as income, consumption and living standards.

The World Ahead 2022: Adjusting to New Realities

A few weeks ago The Economist published The World  Ahead 2022, its 36th annual look at the economic, political, social and cultural trends that will likely shape the coming year. “If 2021 was the year the world turned the tide against the pandemic, 2022 will be dominated by the need to adjust to new realities, both in areas reshaped by the crisis (the new world of work, the future of travel) and as deeper trends reassert themselves (the rise of China, accelerating climate change),” wrote the issue’s editor Tom Sandage.

Here are the top ten major trends in The World Ahead 2022:

New Ways of Understanding Human Behavior

“It is often said that no person is an island and it takes a village to raise a child, but psychology has largely lacked the scientific evidence to quantify and characterize these aphorisms,” wrote MIT professor Alex (Sandy) Pentland in Contextualizing Human Psychology, - an article published in the August, 2020 issue of Technology, Mind and Behavior, a journal of the American Psychological Association. “As a result, experimental focus is usually on more easily quantifiable individual traits and behaviors.”

“In the last decade, however, digital data from online interactions, cell phones, and credit cards have allowed us to precisely quantify large-scale social behavior at a very fine level of detail. The little data breadcrumbs that we leave behind as we move around in the world are enabling new ways of understanding human behavior, giving rise to the emerging discipline of computational social science. “[T]hese new tools can help relate individual traits to the surrounding social context and thus better explain life outcomes and societal characteristics.” 

The article illustrated the advances and challenges of data-driven predictions by discussing a 2017 mass collaboration experiment. The experiment asked each of 160 academic teams to predict six life outcomes, - such as a child’s grade point average and whether a family would be evicted from their home, - by analyzing development data of over 4.200 at-risk children from the Fragile Families and Child Wellbeing Study. These data had been collected by interviewing primary caregivers over more than 15 years, as well as other assessments including early childhood education and the children’s scores on a variety of standard tests. Additional information was provided on the parents, including medical, employment, and incarceration histories, religion, and child care practices. Almost 13,000 measurements were made for each child and their family.

A Winning Strategy for the Post-Pandemic “New Normal”

“A winning digital strategy requires new twists to familiar moves,” said a recent McKinsey article, Strategy for a digital world. “Competitive differentiation, now more than ever, emerges from superior digital capabilities and technology endowment, more agile delivery, and a progressively more tech-savvy C-suite.”

According to the latest McKinsey Global Survey on digital strategy, the pandemic has sped up the adoption of digital technologies by several years. While the imperative for a strategic approach to technology is universal, the survey found that some companies are already leading the pack because they have better overall technology capabilities, talent, leadership, and resources, and their superior technology endowment is linked to better economic outcomes.

The pandemic has accelerated the pace of change of the leading technology companies as well as the industry leaders who’ve been investing heavily in new digital-enabled strategies and business models, widening the gap between these top economic performers and all other companies. At the same time, the survey showed that many of the organizations that are being left behind could be missing opportunities to catch up by investing in the areas of their business most at risk of digital advances.

Traditional legacy companies should revisit the classic strategies that may have worked well for them in decades past but that must now be updated given the accelerated pace of digital disruption. The McKinsey article offers a road map for so doing based on five major changes.

Is the Metaverse the Next Major Phase of the Internet?

“Don’t mock the metaverse,” said The Economist in a November 20 article. “There are good reasons to take the metaverse seriously. One is historical: as computers have become more capable, the experiences which they generate have become richer. The internet began its life displaying nothing more exciting than white text on a black background. Flat images were added in the 1990s. Video came to dominate in the 2010s. On that reading, a move into three dimensions is a logical consequence of the steady growth in computing power.”

“The metaverse is already here. It’s just not evenly distributed,” the article added. “The video-game industry - the only type of entertainment fully exposed to the compounding power of Moore’s law - has been selling virtual worlds for years.” Online games like World of Warcraft, Fortnite, and Roblox have hundreds of millions of users, and their gaming companies have valuations in the tens of billions, - evidence that immersive virtual worlds can be popular and profitable. “It is hard to argue that an idea will never catch on when, for millions of people, it already has.”

3-D virtual environments have had limited success beyond the video-game industry. But this could change. Leading technology companies have announced plans to expand their use in business, education, social media, and other so-called serious applications. On October 28, Mark Zuckerberg announced his commitment to a metaverse strategy by rebranding Facebook as Meta Platforms. A week or so later, Satya Nadella shared Microsoft’s metaverse plans, starting with enabling users of Mesh for Microsoft Teams to interact and collaborate in 3-D immersive workspaces.

Technology’s Role in Society: It’s Complicated

“Welcome to the future - not 2021, as you might have been expecting, but 2025, or even 2030, depending on whom you ask,” said The Economist in a  November, 2020 article. “The adoption of new technological behaviours in response to the pandemic, from video-conferencing to online shopping, means usage has already reached levels that were not expected for many more years.”

For years, companies and governments found all kinds of reasons for not embracing work from home, virtual meetings, telemedicine, online learning, and other digital applications. But, the pandemic forced us to accelerate the digital transformations of the economy and society to help us cope with the crisis. And, not only have these digital applications worked remarkably well, but they offer a number of important benefits, like not waiting for a straightforward doctor diagnosis in a room full of sick people, and not having to travel for hours to participate in a 45 minute meeting.

Post-pandemic, how much will things snap back?, asked The Economist. “Clearly the world is not going to return to its pre-pandemic state…  some new behaviours will stick, but not all, and the result will be somewhere in the middle. Exactly where will have enormous implications: for transport patterns, property prices and the layout of cities, among other things.”

The societal implications of technological transformations are difficult to anticipate, given the rapid changes we’ve been going through in the last few decades, let alone in the last two years. This topic was directly addressed in Technology’s Role in Society: It’s Complicated, the Fall 2021 issue of Footnotes, a publication of the American Sociological Association. The issue includes nine essays on the various ways technology impacts out lives. “As technology continues to evolve at breakneck speed, we find ourselves constantly adapting and keeping up with the latest advancements,” said its Introduction article.

The Evolution of Enterprise Architecture in an Increasingly Digital World

“What does it take for traditional companies to create value with digital technology?,” asked a McKinsey article published in November of 2018. Based on its research, the article suggested that “successful digital reinventors - digital natives and digitally transformed incumbents - employ a range of approaches, such as investing boldly and adopting cutting-edge technologies at scale.” However, the article warned, such efforts can run into serious difficulties. “In our experience, a push to launch more digital applications can make a company’s technology landscape increasingly complex and difficult to manage, to the point that it impedes transformation programs.”

A few months ago, I wrote about the evolving role of the CIO, based on a survey of over 500 CIOs and related technology leaders. Almost all of the surveyed CIOs agreed that their responsibilities will become more strategic in the coming years, uniting their company’s business and technology strategies and managing increasingly complex and difficult digital transformations.

This strategic role of the CIO is in turn driving the evolution of their enterprise-architecture (EA) teams. Traditionally, enterprise architects have been responsible for translating business needs into IT requirements. A major part of their job is making sure that their company’s IT systems work together to  enable and support the company’s overall digital strategy. And increasingly, EA teams have the primary responsibility for managing the technological complexity inherent in digital transformations.

How to Effectively Manage a Company’s Digital Transformation

The adoption of new digital technologies in response to the pandemic has reached levels that weren’t expected for many year, - and those changes are likely be long lasting. A few months ago, for example, a McKinsey survey of global executives found that the pandemic has accelerated the digitization of their customer and supply-chain interactions, their internal operation, and the share of digitally-enabled products and services in their portfolios by roughly three to four years.

“Faced with the pandemic, firms did things that once seemed impossible - sometimes overnight,” noted Forrester Research in an online event that took place earlier this year. “Under the relentless pressure of new customer realities, the future came into focus: The value of your company depends on how customer-obsessed, resilient, creative, and adaptive you are in jumping to the next growth curve in your industry. … 2021 will be the year that every company - not just the 15% of firms that were already digitally savvy - doubles down on technology-fueled experiences, operations, products, and ecosystems.”

But, what should the vast majority of less digitally savvy companies do to embrace the changes they were forced to make in record time to deal with the immediate crisis? How to Speed Up Your Digital Transformation, a recent Harvard Business Review article by Benjamin Mueller and Jens Lauterbach, provides some answers to this question.

“The pandemic has given many organizations an unexpected crash course in digitalization,” wrote the authors. “While much progress has been made - from hardware and infrastructure to updated work processes and a rejuvenated corporate culture - many organizations are confronting the question of how to integrate fragmented and often makeshift digitalization efforts in a way that’s sustainable. … This is particularly pertinent for small and medium-sized organizations that need to be more targeted in their efforts and may not have the resources to engage in the ‘fail fast’ approach often heralded by the larger poster children of the digitalization movement.”

How Has Working from Home Worked Out So Far?

“COVID-19 triggered a mass social experiment in working from home (WFH),” said economists Jose Maria Barrero, Nicholas Bloom, and Stephen J. Davis in Why Working from Home Will Stick, a paper published in April of 2021 by the National Bureau of Economics Research (NBER). “Americans, for example, supplied roughly half of paid workhours from home between April and December 2020, as compared to five percent before the pandemic. This seismic shift in working arrangements has attracted no shortage of opinions about whether WFH will stick.”

Working from home (WFH) has been around for decades, modestly growing in the 1990s with the rise of the Internet. The share of WFH three or more days per week was under 1% in 1980, 2.4% in 2010, and 4.0% in 2018. Then came Covid-19, forcing tens of millions around the world to work from home and triggering a mass workplace experiment that broke through the technological and cultural barriers that had prevented its adoption in the past.

To investigate whether WFH will stick, the authors of the NBER paper devised a survey that asked questions about working arrangements and personal experiences with WFH during the pandemic, as well as worker preferences and employer plans after the pandemic ends. The survey was conducted monthly between May 2020 and March 2021, by which time it had collected 28,597 valid responses from 20-64 years old US workers, of which 43.8% were female. The typical respondent was 40 to 50 years old, with one to three years of college, who earned $40 to $50 thousand in 2019.

Let me discuss a few of the survey’s questions and findings.

Which Colleges and College Programs Give Students the Best Bang for their Buck?

“The decision not to attend college for fear that it’s a bad deal is among the most economically irrational decisions anybody could make in 2014,” wrote NY Times journalist David Leonhardt in Is College Worth It? in May of 2014. “Over the long run, college is cheaper than free,” he added, citing an article by MIT economist David Autor which pointed out that a college-educated worker can expect an additional lifetime earning of over $500,000 compared to one whose highest degree is a high school diploma. Experts and journalists questioning the value of a college education are most likely obsessing to get their toddlers into an elite nursery school, so they are on-track for the right schools over the ensuing 20 years, added Leonhardt.

In May, 2019 seminar I attended, Autor noted that over the last four decades, the US and other industrial economies have seen a remarkable rise in wage inequality by educational attainment, with the earnings of the most-educated increasing, and the earnings of the least-educated falling in real terms. Since the 1980s, the earnings of those with a four year college degree have risen by 40% to 60%, while the earnings of those with a high school education or less have fallen among men and barely changed among women.

Every year, the US Bureau of Labor Statistics publishes a set of earning projections by educational attainment. Their 2020 projections showed that the median weekly earnings for all workers is $1,029; for those with less than a high school degree it is $619; high school diploma - $781; some college, no degree - $877; associate’s degree - $938; bachelor’s degree - $1,305; master’s degree - $1,545; doctoral degree - $1,885; and professional degree - $1,893.

Beyond these aggregate numbers, which institutions of higher education give students the best economic returns, that is, the best bang for their buck. In April of 2020, Third Way, a public policy think tank, published a report that introduced a new approach for estimating the economic return of an education, - that is, the Price-to-Earnings Premium (PEP), - based on the amount of time it generally takes a student to recoup the cost of obtaining a credential at a particular school.

Impact of Covid-19 on Job Automation

“Why are there still so many jobs?,” asked MIT economist David Autor in a 2015 article on the history of workplace automation. Given that technologies have been automating human work for the past couple of centuries,“should we not be somewhat surprised that technological change hasn’t already wiped out employment for the vast majority of workers?”

As Autor explained in the article, the answer is based on an economic reality that’s frequently overlooked. “Automation does indeed substitute for labor - as it is typically intended to do. However, automation also complements labor, raises output in ways that lead to higher demand for labor, and interacts with adjustments in labor supply. … journalists and even expert commentators tend to overstate the extent of machine substitution for human labor and ignore the strong complementarities between automation and labor that increase productivity, raise earnings, and augment demand for labor.”

Professor Autor was co-chair of MIT’s Work of the Future Task Force, which was launched in the spring of 2018 to better understand the impact AI and automation on jobs. The Task Force released an interim report in September of 2019. Its overriding conclusion was that the likelihood that AI and automation would wipe out major workforce sectors in the near future was exaggerated.

However, it raised important reasons for concern, especially the rising polarization of employment and wage distribution over the past few decades, which has disproportionately benefited high-skilled professionals while reducing opportunities for mid- and low-skilled workers. The report emphasized that “at a time of historic income inequality, a critical challenge is not necessarily a lack of jobs, but the low quality of many jobs and the resulting lack of viable careers for many people, particularly workers without college degrees.”

The Covid-19 pandemic came a few months later, pretty much turning our world upside down.
