It's clear to me that (1) a lot of billionaires believe amazingly stupid things, and (2) a big part of this is that they surround themselves with a bubble of sycophants. Apparently having people tell you 24/7 how amazing and special you are sometimes leads to delusional behavior.
But now regular people can get the same uncritical, fawning affirmations from an LLM. And it's clearly already messing some people up.
I expect there to be huge commercial pressure to suck up to users and tell them they're brilliant. And I expect the long-term results will be as bad as the way social media optimizes for filter bubbles and rage bait.
