I'm not super qualified to answer as I haven't gone deep into AI at all. But from my limited observations I'd say yes and no. You generally aren't copy/pasting entire features, just snippets that you yourself have to string together in a sensible way. Of course there are lots of people who still do this and what's why I find most people in this industry infuriating to work with. It's all good when it's boilerplate, and that's actually my primary use of "AI"—it's essentially been a snippets replacement (and is quite good at that).
