Seriously. The AI psychosis that has people actually believing this stuff is far scarier to me than what might maybe possibly could happen if AI somehow actually performs to the level that the people selling it say it will.
One thing I have seen no evidence of is AI being smarter than the smartest humans. It's still just a search engine (with an impressive human language UI) of existing human knowledge. It cannot do anything it has not been trained on.
LLM: crawl the entire Internet and train a model. When you ask it a question, it uses that model to spit out an answer. Worse than a search engine though, if it can't come up with a good answer it just makes shit up
Both use the same sources of information. Neither can produce a (correct) answer that doesn't exist somewhere in that information source
