The Future of Work from Home (WFH)

Work from home (WFH) has been around for decades. The share of people working from home three or more days per week was under 1% in 1980, growing modestly with the rise of the Internet to around 2.4% in 2010 and 4% 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 WFH adoption in the past.

Since May of 2020, economists Jose Maria Barrero (Instituto Tecnológico Autónomo de México), Nicholas Bloom (Stanford University), and Stephen J. Davis (University of Chicago) have been conducting monthly surveys to track the evolution of WFH. Their surveys ask questions about working arrangements during the pandemic, as well as about worker preferences and employer plans post-pandemic. Typical respondent are 40 to 50 years old, have one to three years of college, and earned $40 to $50 thousand in 2019.

I’ve been tracking the evolution of WFH by following their monthly surveys. One of their first surveys found that the percentage of paid full days worked from home once COVID hit in April of 2020 was 61.4%, a huge increase from their 4.8% WFH estimate just before COVID. The percentage then started to decline in subsequent months. One year later WFH was around 45%. 

In an April 2021 working paper, “Why Working from Home Will Stick,” Barrero, Bloom, and Davis predicted that the shift to work from home would be one of the biggest legacies of the pandemic. They projected that “American workers will supply about 20 percent of full workdays from home in the post-pandemic economy, four times the pre-COVID level. Desires to work from home part of the week are pervasive across groups defined by age, education, gender, earnings, and family circumstances.” They estimated that higher levels of WFH would boost productivity by about 4.6%, with over half of the productivity gain reflecting the WFH savings in commuting time.

A Planetwide Vision of the Future of Global Supply Chains

“The central purpose of supply chains is to fulfill the needs and wants of humanity — delivering all the food, medicine, energy, apparel, and other worldly goods needed by the eight billion people in the planet,” wrote MIT professor Yossi Sheffi in the preface of his 2023 book, The Magic Conveyor Belt: Supply Chains, A.I. and the Future of Work. “The societal and economic spasms of the early 2020s highlighted the crucial role of world-spanning supply chains in the modern global economy, as well as the growing role of digital technology, including A.I. and automation, in the future economy.”

I’ve been following the evolution of global supply chains for the past three decades. The 1990s ushered a golden age of globalization, when the world seemed to be coming together. Thomas Friedman’s The World is Flat became an international best-seller in 2005, nicely explaining what globalization was all about, including the key forces that contributed to the flattening of the world, from the explosive growth of the Internet to the rise of just-in-time global supply chains.

My interest in global supply chains increased significantly in the mid 2010s, as a result of my growing interest in the business applications of blockchain technologies. In 2016, the World Economic Forum (WEF) included blockchain in its annual list of Top Emerging Technologies. The WEF report compared blockchain to the Internet, noting that “Like the Internet, the blockchain is an open, global infrastructure upon which other technologies and applications can be built. And like the Internet, it allows people to bypass traditional intermediaries in their dealings with each other, thereby lowering or even eliminating transaction costs.”

I became convinced that global supply chains would emerge as the killer app for enterprise blockchain applications. Over the following years, I closely tracked the evolution of blockchain-based supply chain systems. I assumed that, much like the Internet in the 1990s and Linux in the 2000s, it was just a matter of time before blockchain technologies would be widely embraced in the business world.

But, as we now know, things didn’t quite turn out as I had expected. “Blockchain, the technology underpinning bitcoin and other cryptocurrencies, for years has been viewed by some companies as a way to drive industry-transforming projects, among them the tracking of assets through complex supply chains. So far that hasn’t happened,” wrote the Wall Street Journal in a December 2022 article, “Blockchain Fails to Gain Traction in the Enterprise.”

Business Strategy in the Emerging AI Era

“AI is changing the cost and availability of expertise, and that will fundamentally alter how businesses organize and compete,” said “Strategy in an Era of Abundant Expertise,” a Harvard Business Rreview (HBR) article by Harvard Business School professor Karim R. Lakhani and Microsoft corporate strategists Bobby Yerramilli-Rao, John Corwin, and Yang Li. At its most basic level, a business can be thought of as a bundle of expertise organized to accomplish specific tasks for competitive advantage. The evolution of this expertise defines the evolution of the business.

The article defines expertise as “a combination of deep theoretical knowledge and practical know-how in a specific domain.” Expertise can take many forms, such as deep subject matter knowledge in a specific field, — like manufacturing, software engineering, or a medical specialty, — and the skills needed to successfully run a business, — e.g., marketing, sales, operations, finance. “Companies create  value by applying their expertise efficiently at scale to solve problems for their customers. Typically they possess it in a variety of areas, but most differentiate themselves through their unique proficiency in just a handful of activities that are fundamental to how they create competitive advantage.”

While critical to a company’s success, keeping up with technological advances can be quite challenging for two key reasons. First, expertise is constantly expanding, making it difficult to stay abreast of advances and insights in a competitive global marketplace. And second, the cost of accessing that expertise is constantly falling, lowering the barrier for new, fast moving competitors. The interplay between these two forces, — “the increasing amount of expertise required to create value and the decreasing cost of accessing that expertise — shapes companies and affects the scope of their operations.”

While AI Has Been Eating Computing, Philosophy May Be Ready to Make a Meal of AI

In his legendary 1965 paper, “The Future of Integrated Circuits,” Intel co-founder Gordon Moore first made the empirical observation that the number of components in integrated circuits had been doubling every year since their invention in 1958. Moore predicted that the trend would continue for at least ten years, a prediction he subsequently changed to a doubling every two years. The semi-log graphs associated with Moore’s Law have since become a visual metaphor for the revolution unleashed by the exponential improvements of just about all digital components, from processing speeds and storage capacity to networking bandwidth and pixels.

Moore’s Law has had quite a run, but like all things based on exponential improvements, it eventually slowed down and flattened out in the 2010s. What will now drive computing in the post-Moore’s-Law era?

Software has been a key driver of computing since the 1980s. In a 2011 essay, “Software is Eating the World,” technologist and investor Marc Andreessen wrote that “we are in the middle of a dramatic and broad technological and economic shift in which software companies are poised to take over large swathes of the economy. More and more major businesses and industries are being run on software and delivered as online services — from movies to agriculture to national defense.” Entrepreneurial companies all over the world have been disrupting established industries, with innovative software-based solutions.

In 2017, Nvidia CEO and co-founder Jensen Huang boldly updated Andreessen’s essay by predicting that “Software Is Eating the World but AI is Going to Eat Software.” In 2024, he further predicted that “the future of coding as a career might already be dead in the water with the imminent prevalence of AI.

“But even as software eats the world and AI gobbles up software, what disrupter appears ready to make a meal of AI?,” asked MIT researchers Michael Schrage and David Kiron in “Philosophy Eats AI,” a recent article in MITSloan Management Review. “The answer is hiding in plain sight. It challenges business and technology leaders alike to rethink their investment in and relationship with artificial intelligence. There is no escaping this disrupter; it infiltrates the training sets and neural nets of every large language model (LLM) worldwide.”
