The Emergence of a Blockchain-Based Token Economy

Blockchain Revolution, published in May of 2016 by Don Tapscott and Alex Tapscott, was one of the first books that explained the promise of blockchain technologies to the general public.  Its central argument is that for nearly four decades, the Internet has been great for reducing the costs of searching, collaborating, and exchanging information.  But, it has serious limitations for business and economic activity.  “Doing business on the Internet requires a leap of faith,” the book noted.  The Internet was designed to move information, but it’s lacked the necessary trust, security and privacy safeguards to move assets of value.  With blockchain, we’re now seeing the emergence of such an Internet of value.  “Now for the first time ever we have a native digital medium for value, through which we can manage, store, and transfer any asset.”

An updated edition of Blockchain Revolution was published this past June.  A lot has happened with blockchain in the intervening two years.  The updated edition explains some of these recent developments in a new preface, including cryptoassets, permissioned networks, identity and supply chains.  I’ll focus my comments on the emergence of a blockchain-based token economy, driven by the explosive growth in the value and variety of cryptoassets.

When the original book was published, the entire cryptoasset market had a value of $9 billion, - mostly dominated by the value of Bitcoin at $7 billions, while Ether, the Ethereum cryptocurreny, had reached around $1 billion.  The new edition estimates that as of March, 2018, the cryptoasset market was around $400 billion in size, a value subject to rapid fluctuations.  In addition, a wide variety of cryptoassets have been developed over the past two years. 

What Machine Learning Can and Cannot Do

Artificial intelligence is rapidly becoming one of the most important technologies of our era.  Every day we can read about the latest AI advances from startups and large companies.  Over the past few years, the necessary ingredients have come together to take AI across the threshold: powerful, inexpensive computer technologies; huge amounts of data; and advanced algorithms, especially machine learning.  Machine learning has enabled AI to get around one of its biggest obstacles, - the so-called Polanyi’s paradox.

Explicit knowledge is formal, codified, and can be readily explained to people and captured in a computer program.  But, tacit knowledge, a concept first introduced in the 1950s by scientist and philosopher Michael Polanyi, is the kind of knowledge we’re often not aware we have, and is therefore difficult to transfer to another person, let alone capture in a computer program.

“We can know more than we can tell,” said Polanyi in what’s become known as Polanyi’s paradox.  This common sense phrase succinctly captures the fact that we tacitly know a lot about the way the world works, yet aren’t able to explicitly describe this knowledge.  Tacit knowledge is best transmitted through personal interactions and practical experiences.  Everyday examples include speaking a language, riding a bike, and easily recognizing many different people, animals and objects.

Machine learning, and related advances like deep learning, have enabled computers to acquire tacit knowledge by being trained with lots and lots of sample inputs, thus learning by analyzing large amounts of data instead of being explicitly programmed.  Machine learning methods are now being applied to vision, speech recognition, language translation, and other capabilities that not long ago seemed impossible but are now approaching or surpassing human levels of performance in a number of domains.

The Transformative Power of Analytics - The Houston Astros: a Case Study

In 2013, the Houston Astros finished the season with a 51-111 record, - the worst record in the history of the franchise, having also lost over 100 games in the previous two years.  In 2017, the Astros won 101 games, finished first in the American League West Division, and went on to win their first ever World Series.  How did the Astros go from worst team record to first World Series victory in only four years?

The answer, in a nutshell, is analytics.  In December, 2011 the Astros hired Jeff Luhnow from the St Louis Cardinals as their General Manager.  As VP of scouting and player development in St Louis, Luhnow built a strong analytics department and enjoyed great success as one of the top talent producers in baseball, helping the Cardinals win the 2011 World Series as well as reach the playoffs from 2012 to 2015.  Luhnow then brought his analytics and management skills to Houston and proceeded to transform the team into a top contender in a short few years.

Today, just every major sports team makes extensive use of sports analytics, but none more so than Major League Baseball (MLB) teams.  Baseball has long been a game of statistics, collecting and analyzing vast amounts of data going back to the founding of the MLB in the years following the Civil War. 

Top MLB players are constantly compared not just to other contemporaneous players, but to other top players across the long history of the game, - a history that was very nicely depicted in Baseball, Ken Burns excellent documentary miniseries. Babe Ruth, Willie Mays, Mickey Mantle, Hank Aaron and countless other players are never forgotten in the world of baseball statistics.  For those of us who are fans, - as I am, not surprisingly given my Cuban roots, - baseball’s rich history is a major part of our enjoyment of the game. 

Are Innovation and R&D Yielding Decreasing Returns?

Given the pace of technological change, we tend to think of our age as the most innovative ever.  But over the past several years, a number of economists have argued that increasing R&D efforts are yielding decreasing returns.

Has the ideas machine broken down?, asked The Economist  in a January, 2012 article that examined the growing concerns that we may be in a long-term period of slow innovation despite our rapidly advancing technologies.  “With the pace of technological change making heads spin, we tend to think of our age as the most innovative ever,” said The Economist.  “We have smartphones and supercomputers, big data and nanotechnologies, gene therapy and stem-cell transplants. Governments, universities and firms together spend around $1.4 trillion a year on R&D, more than ever before.”  But, perhaps these don’t quite compare with modern sanitation, electricity, cars, planes, the telephone, and antibiotics.  These innovations, first developed in the late 19th and early 20th century, have long been transforming the lives of billions.

In a September, 2012 paper, Northwestern University economist Robert Gordon questioned the generally accepted assumption that economic growth is a continuous process that will persist forever.  He wrote that the slow growth we’ve been experiencing in the US and other advanced economies isn’t cyclical, but rather evidence that long-term economic growth may be grinding to a halt.

The rapid growth and rising per-capita incomes we experienced at the height of the Industrial Revolution, - between 1870 and 1970, - may have been a unique episode in human history.  Since the 1970s, US productivity and income growth have dipped sharply except for an Internet-driven productivity boost between1996 and 2004.  Innovation may be hitting a wall of diminishing returns.  There was little growth before 1800, and there might conceivable be little growth in the future.

A similar pessimistic view was expressed by George Mason University economist Tyler Cowen in his 2011 book The Great Stagnation.  According to Cowen, over the past two centuries the US economy has enjoyed lots of low-hanging fruit, including a vast, resource rich land, waves of immigrant labor, access to education and the technological advances of the Industrial Revolution.  But, Cowen believes that we are at a technological plateau, and wonders whether long term growth is still possible because the supply of low-hanging economic fruit is nearly exhausted.

Getting on the AI Learning Curve: A Pragmatic, Incremental Approach

After decades of promise and hype, AI is now seemingly everywhere.  Over the past several years, the necessary ingredients have come together to propel AI beyond the research labs into the marketplace: powerful, inexpensive computer technologies; huge amounts of data; and advanced algorithms including machine learning.

While AI is likely to become one of the most important technologies of our era, we’re still in the early stages of deployment, especially outside leading-edge technology companies.  But, as AI continues its rapid progress, it’s not too early to ask a few important questions: What is AI’s overall value to the economy? What are the biggest application opportunities?; and, what are AI’s most serious challenges and limitations?

To address these questions, McKinsey recently published a discussion paper on the marketplace potential of AI.  The paper is particularly focused on machine learning and related technologies, and is based on a detail analysis of more that 400 use cases across 19 industries and 9 business functions.

“Two-thirds of the opportunities to use AI are in improving the performance of existing analytical use cases,” is the paper’s overriding finding.  This is a very interesting insight.  AI is now being successfully applied to tasks that not long ago were viewed as the exclusive domain of humans, - machine translation, natural language processing, defeating the world’s top Go players, - but only 16% of the use cases studied by McKinsey are greenfield cases, where only machine learning techniques can be used.  For the vast majority of the use cases, 69%, the key value of machine learning is to improve performance beyond that provided by traditional analytic techniques.  And, in the remaining 15% of cases, machine learning provided limited additional performance over existing analytical methods.
