Well that's funny, because you were making some pretty blanket statements upstream about how they "never" do this and "always" do that. And yet your experience seems extremely limited and niche, by your own admission.
Maybe you should experiment a little more. I think you will quickly learn that your previous impression is wrong. The days of them being merely some sort of jumped up autocomplete are years gone.
Look, I know you believe in the Mystical GPU Sky Fairy, but AI is not in any sense "intelligent". It doesn't think. It's a pattern-matching system like an Eliza bot with a huge corpus to draw from.
It is not thinking. It cannot think. It cannot create.
Granted, I've only asked it about some of the weirdly specific technological niche that my code inhabits.
