Harvard Business School Professor and Author — on Innovation, the Technology Gold Rush of AI, What Writing a Book Really Teaches, and How to Grow Leaders Who Stay True to Themselves
Shane Greenstein has spent his career at Harvard Business School asking one deceptively simple question: how did the world get rich? Not in the financial sense, but in the civilizational one — how did we get from a world where half of all babies died before age ten to the world we live in now? His answer, refined over decades of research and three academic appointments, is that the processes that translate new technology into commercial markets are the engine of human progress. And in this episode of Be Yourself Podcast, he breaks down exactly how that engine works.
Shane explains the crucial distinction between technological breakthroughs and commercial breakthroughs — and why the latter, not the former, is what changes how everybody behaves. He walks through real examples: Netflix figuring out how to stream reliably to your home, a simple pharmacy reminder that took years of database integration to make seamless, and why AI today is following a pattern he calls the technology gold rush — a moment when every participant in the market is surprised by the discovery of value, and a rational frenzy follows.
The conversation moves from forecasting to writing. Shane shares what he learned from writing his book on the commercialization of the internet — the moment halfway through when he realized he didn't actually understand what he was writing about, and why that is the point. He talks about who should try writing a book, the value of deadlines, and why the best piece of advice he received about writing — write a short book — was the one he ignored first. And he closes with what growing the next generation of leaders actually requires: pluralism, turnover, and the courage to stay true to yourself.
Shane Greenstein is a professor at Harvard Business School, where he has been on the faculty for ten years. Before that he held positions at Northwestern University and the University of Illinois at Urbana-Champaign. He studies innovation economics — specifically how new technologies get translated into commercial markets and how that translation process drives economic growth and human welfare.
He is the author of How the Internet Became Commercial: Innovation, Privatization, and the Birth of a New Network, published by Princeton University Press. The book is a long narrative history of one of the most consequential commercial transformations of the twentieth century, told from the simultaneous perspectives of multiple participants — Wall Street, Silicon Valley, Midwestern research institutions — and built from years of short essays that Shane had to learn, halfway through writing, how to weave into a coherent whole.
Shane approaches forecasting with unusual discipline: rather than making bold predictions, he identifies historical patterns — like the technology gold rush — and asks what we would expect to see if those patterns hold. It's a method born from being accountable to students who come back and tell him when he got it wrong. He is currently writing a new book on commercial breakthroughs, and has outlined it fifteen times before diving in.
You don't understand it unless you can explain it quickly.
A technology gold rush is one in which every participant in the market is surprised by the discovery of value.
All of us have a little bit of human kindness and a little bit of human decency in us, but it is so easy to forget that when you have some fireworks in front of you.
