We're not such a smart species. It's not like we managed so far. We're just adding unsolved problems, and distract ourselves with even bigger problems. The world could have been fed and clothed by the mid 20th century and we could have solved climate change by the 1980s (talking out of my ass here but with confidence in my general point with that), but instead we now throw everything into the furnace. in the hopes it will create a deus ex machina, like in that very bad Isaac Asimov story. I think we are absolutely capable of lobotomizing ourselves (as a species) like a toddler playing with an electrical socket shocking itself. I don't say this to be snarky, I honestly think we're that unserious and ignorant about what we do and the environment we do it in.
But I also really should look into what you answered about LLM learning from themselves, I heard it mentioned before but I still have no real clue. I will try to rectify that. I mean, I really, really want to be wrong on this, only a monster wouldn't.
