What's changed since the "pause AI" letter six months ago?

Well, that didn't happen, obviously. I sat down with MIT professor Max Tegmark, the founder and president of FLI, to take stock of what has happened since. Here are highlights of our conversation. On shifting the Overton window on AI risk: Tegmark told me that in conversations with AI researchers and tech CEOs, it had become clear that there was a huge amount of anxiety about the existential risk AI poses, but nobody felt they could speak about it openly "for fear of being ridiculed as Luddite scaremongerers." "The key goal of the letter was to mainstream the conversation, to move the Overton window so that people felt safe expressing these concerns," he says.
