Lack of imagination is also part of it I'm sure... looking at the silly things some people ask AI (tbh so do I though, out of curiosity) but failing to use it for what's truly important and where it can add value (this is what I try to pursue, mostly by just trying it a lot on anything, without stopping to think for myself).
On a side note, I really feel bad for Gen Z. Society has forced them to push AI as far as possible. They probably are the most aware of its limitations. Yet they are also the least able to criticize it without career repercussions.
I suspect this will change soon as more people come around to the fact that their chat bot is another tool just like Google search.
I used to think how wrong it was to compare an LLM to a search engine but have realized over time that despite being wrong, it's still a better mental model because it gets a fundamental detail right; LLMs are tools, they aren't agents, they aren't autonomous, they don't understand things, at least not in the way a human would understand them.
And this all ties back to the OP, that's the problem with calling them "smarter". Yes they can solve ancient math problems that humans failed at for many years and yet at the same time cannot be trusted to take a drive through order.
We need to stop seeing LLMs as a replacement for human cognition and instead appreciate what each form of "intelligence" brings to the table.
