John is joined by journalist Karen Hao to discuss her new book, “Empire of AI: Dreams and Nightmares in Sam Altman's OpenAI,” and both the promise and the perils of the coming age of artificial intelligence. Hao explains how OpenAI went from being an altruistic nonprofit dedicated to ensuring that A.I. would “benefit all of humanity” to a burgeoning commercial colossus valued at north of $300 billion; how Altman wrested control of the company from his co-founder Elon Musk; why skepticism is warranted regarding the claims that superhuman A.I. is inevitable; and how that narrative, true or not, serves the economic and political interests of the cabal of tech bros who are A.I.’s most fervent boosters.
