Maybe. So far it seems to be a lot better at creative idea generation than at writing correct code, though apparently these "agentic" modes can often get close enough after enough iteration. (I haven't tried things like Cursor yet.) I agree that it's also not currently capable of judging those creative ideas, so I have to do that.
This sort of discourse really grinds my gears. The framing of it, the conceptualization. It's not creative at all, any more than taking the sum of text on a topic, and throwing a dart at it. It's a mild, short step beyond a weighted random, and certainly not capable of any real creativity. Myriads of HN enthusiasts often chime in here "Are humans any more creative" and other blather. Well, that's a whataboutism, and…
Pointing out that your working definition excludes reality isn't whataboutism, it's pointing out an isolated demand for rigor.
If you cannot clearly articulate how human creativity (the only other type of creativity that exists) is not impugned by the definition you're using as evidence that creativity "does not exist in the AI sphere", you're not arguing from a place of knowledge. Your assertion is just as much sophistry as the people who assert it is creativity. Unlike them, however, you're having to argue against instances where it does appear creative.
For my own two cents, I don't claim to fully understand how human creativity emerges, but I am confident that all human creative works rest heavily on a foundation of the synthesis of author's previous experiences, both personal and of others' creative works - and often more heavily the latter. If your justification for a lack of creativity is that LLMs are merely synthesizing from previous works, then your argument falls flat.
