From the authors of the best-selling The Second Machine Age, a leader’s guide to success in a rapidly changing economy.
We live in strange times. A machine plays the strategy game Go better than any human; upstarts like Apple and Google destroy industry stalwarts such as Nokia; ideas from the crowd are repeatedly more innovative than corporate research labs. MIT’s Andrew McAfee and Erik Brynjolfsson know what it takes to master this digital-powered shift: we must rethink the integration of minds and machines, of products and platforms, and of the core and the crowd. In all three cases, the balance now favors the second element of the pair, with massive implications for how we run our companies and live our lives.
In the tradition of agenda-setting classics like Clay Christensen’s The Innovator’s Dilemma, McAfee and Brynjolfsson deliver both a penetrating analysis of a new world and a toolkit for thriving in it. For startups and established businesses, or for anyone interested in what the future holds, Machine, Platform, Crowd is essential listening.
- Andrew McAfee and Erik Brynjolfsson have done it again. ‘Machine, Platform, Crowd’ is a lucid and timely exploration of three powerful trends unleashed by the digital revolution. They describe the ‘three rebalancings’: first, as machine learning either complements or supplants human minds, secondly , as platforms drive the selection, production and distribution of products and services, and thirdly, as on-line crowds increasingly augment or surpass the core functions of companies.
Although the authors don’t put it this way, there are essentially three economic drivers of the ‘triple revolution’. First, the “free, perfect and instant economics of digital information goods in a time of pervasive networks” which means that “the marginal cost of an additional digital copy is (almost) zero”. Second, the positive network effects from the growth in user interaction. As they put it, “Networked goods can become more valuable as more people use them. The result is ‘demand side economies of scale’, giving an advantage to bigger networks”.
The third driver is the distinctive ability of multi-sided platforms to subsidise one or more set of users in order to incentivise the participation of other sets of users. Digital technology allows many platforms to offer free or discounted services which draw in consumers. This encourages ecosystem growth by attracting more producers or advertisers who pay for the privilege, in turn making it more attractive for other consumers and users.
The book is clearly structured into three sections discussing the title themes, with handy summaries at the end of each chapter. Although the three themes are given equal billing, in the end what dominates is the potential for platforms to capitalise on machine learning and crowd mobilisation. Chapter 7 observes that platforms compete on drawing in users’ contributions and curating them effectively, “but it becomes much more difficult to build a vibrant platform if at least two are already in place”. Network effects and the reluctance of consumers to switch or use more than one platform (or “multi-home”) allows successful platforms to dominate their markets. McAfee and Brynjolfsson are curiously reluctant to use the word, but tendency of platforms towards monopoly is clear. The potentially negative effects of this on competition and innovation are left unexplored, although they would probably need another book to do them justice.
The book also glosses over another distinctive feature of the growth of platform companies: many of today’s giants spent years losing money. Investors have tolerated this, placing faith in the platforms’ ability to turn rapid growth in their user base into longer term profits. They perceive market dominance arising from investing in network effects has long term value. The problem for incumbent companies facing digital disruption is how to secure similar investor indulgence in seeking to transform themselves. The authors argue that there is room for incumbent companies to co-exist with platforms, but they leave little room to doubt that the momentum is with the latter.
The authors end on an optimistic note, saying that “the next few decades should be better than any other […] so far”, although they are careful to describe this as “possibility and a goal”. Indeed, they are suitably humble throughout about making predictions of the disruptive trend that they describe. Amusingly, while the publishers describe the book as a “toolkit” MacAfee and Brynjolfsson say at the outset that they are not offering a “playbook” and that “we suspect that people who offer such a playbook are kidding either themselves or their readers. There is simply too much change and […] uncertainty”. Nevertheless, they have done us all a great service in explaining some of the powerful trends that will shape our future.
- I thought it would be difficult for the authors to top their prior book – The 2nd Machine Age – which presented the underlying principles of the digital age. Yet, they have pulled this off. They do so by building on their prior work and exploring what they see as the three dominant themes of the oncoming digital age: machines, platforms, and crowds. It’s a superb blend of computer science and economics suited for a managerial audience. By exploring the developments in computer science, especially machine learning and artificial intelligence, they predict that more and more human work will be done by machines and economics tells us that we need to invest more in machines. Likewise, the economics of platforms leads the authors to predict the rise of platforms over products because it engenders complementary investments that make the platform more useful. FInally, they argue for a focus on external innovation – the rise of “crowds” which has given rise to the sharing economy and encourages open innovation. What I especially like is that this is a thoughtful book, presenting a compelling set of arguments for how businesses should anticipate and prepare for the second phase of the 2nd machine age. Leveraging theory, analogy, and history, a reader should acquire a nuanced understanding of the digital world and its implications for all businesses, no matter the industry. It is also more directly targeted at business executives. It is a must read!
