After one becomes wealthy, social media easily becomes the only place where anyone says no to them. When everyone who surrounds you tells you "you're absolutely right, let me get that for you", you atrophy the muscle that let's you course correct when you're making a mistake, and when someone disagrees with you it feels that much stronger.

Wealth is not the only way this can happen, you see it with notoriety and power who have gotten used to " being right" (Dawkins comes to mind), and now this experience is being "democratised" by LLMs.
