The first network effect was a phone call (ft. James Gleick)

Shownotes

James Gleick — acclaimed science writer and bestselling author of Chaos: Making a New Science as well as biographies on polymaths Isaac Newton and Richard Feynman — joins Sonal Chokshi and Robert Hackett to discuss his new book, The Telephone: A New History. It is a story of a device — who really invented it, how? — of a network, of a lab, and of how innovation happens.

The telephone was dismissed as a toy or a frivolity — at best, something people could use to listen to concerts or sermons from home. Even with a working invention, everyone was still trying to figure out what a telephone was for, using the framework of what they already knew. Then its users started finding their own answers. Farmers built their own decentralized networks using barbed-wire fences — the “devil’s rope” — and, over time, research at a company built around phone calls helped lay the foundations of modern computing.

This conversation explores the nuances of building at the frontier: competing inventors, the experiments, the “scenius of genius.” Why did established businesses underestimate it? Did the telephone network have to become a monopoly? What made Bell Labs so productive?
And how a single invention could set off a technology revolution
