Most memorable paragraph I read this weekend, from a Wall Street Journal deep dive about how Sam Altman and Elon Musk went from friends to bitter enemies:
In early 2015, Musk and Altman began having regular dinners each Wednesday in the Bay Area. Their conversations tended toward the apocalyptic: how the world might end, how they might prepare for it, to where they might have to flee. A likely cause, they agreed, would be artificial intelligence that grows smarter than humans and impossible to control.
