Ben Chestnut made $6B pretending to be progressive so that his employees would buy into his cult without demanding equity. Honestly the worst part about it is that he has nothing better to do with his life now than punch down on the social network for bland airheads (LinkedIn).

I've said this before but to reiterate: the actual existential threat from AI/LLMs is not that they're going to take our jobs, it's that they're incredibly powerful (and literal) advertising/misinformation/propaganda machines.
