I'm also skeptical that making LLMs a free-for-all will necessarily result in society developing some sort of herd immunity to bullshit. Pointing to your example, the internet started out as a wild west, and I'd say the general public is still highly susceptible to misinformation.
I don't disagree on the dangers of having a relatively small number of leaders at for-profit companies deciding what information we have access to. But I don't think the biggest issue we're facing is someone going to the ChatGPT website and assuming everything it spits out is perfect information.
