Technology has a history of starting out with good intentions, and eventually being leveraged for quite the opposite. On this week’s episode, Adam Fisher, author of Valley of Genius, joins Nick to explain how Silicon Valley--an industry created to advance war research and governmental capacities--was co-opted for commercial, and often sinister, purposes, from election-meddling operatives to racist trolls. Fisher also explains what Mark Zuckerberg, Jack Dorsey, and Elon Musk can learn from their predecessors, before they destroy the world.
