I think crypto companies and AI companies probably intentionally mislead approximately the same amount as one another, but in crypto the average participant is often bagholding a very short term investment and has a direct and tangible incentive to mislead as many people about it as quickly as possible- whereas in AI people mostly just get lost in the sauce with anthropomorphism.

Anecdotally, I see a lot more bold-facing lies by crypto traders or NFT "collectors" than by LLM enthusiasts.
