I think we fear the same things, roughly. My fear is what humans do with any tech we create. Where we differ is that I would prefer things not be built. After a lifetime of watching what we actually do with the things we create, I think we need a bit of a “time out”. Just my 2 cents that won’t change a thing!
The danger I see is related to psychological effects caused by humans using LLMs on other humans. And I don't think that's a scenario anyone is giving much attention to, and it's not that bad (it's bad, but not world end bad).
I totally think we should all build it. To be trained from scratch on cheap commodity hardware, so that a lot of people can _really_ learn it and quickly be literate on it. The only true way of democratizing it. If it's not that way, it's a scam.
