Author Jeanette Winterson has been reading and writing about artificial intelligence and its relationship to humans for years. Her new book, a collection of essays called “12 Bytes: How We Got Here. Where We Might Go Next,” explores these themes. Marketplace’s Kimberly Adams speaks with Winterson, who said she wrote the book because she wanted to understand the implications that AI has for humans — the good and the bad, especially when it comes to AI and robotics. And in that space, Winterson said, a lot of the investment is going toward the good.
