The biggest problem that I have with AI is how people extrapolate out of thin air, going from "LLMs can craft responses that sound exactly like a human" to "LLMs can solve climate change and world hunger". Those are two orthogonal skills and nothing we've seen so far indicates that LLMs would be able to make that jump, any more than I expect someone with a PhD in linguistics to solve problems faced by someone with a PhD in applied physics working on solving nuclear fusion.
