It's mostly beginners thinking of it as a shortcut to making software without learning any of the underlying theory. Basically, why struggle your way through a Rust tutorial on fighting the borrow checker when you can just get AI to do it? Though the issue is as soon as there's something too complex for the AI to figure out, you're out of luck because you've been deliberately avoiding learning the necessary concepts to fix it yourself.

As for whether serious people are pushing it, most actual software engineers, not really, but company management would absolutely like nothing more than to replace all their developers with AI, so yes they're pushing it pretty hard.
