Great discussion on the existential threat of artificial general intelligence with psychologist Steven Pinker and MIT lecturer Lex Fridman. Spoiler: Pinker thinks the arguments for an existential threat are incoherent and downright silly. As usual, Pinker is rational, persuasive and good humored. Fridman's MIT class on artificial intelligence has a great series of lectures by some of the heaviest hitters in the field including Max Tegmark, Ray Kurzweil, Stephen Wolfram, Christof Koch and others, Some are rather technical, but I'm not an software engineer and could follow most of it. Recommended.
