In a way, many “novel” ideas are mathematical restructurings of existing ideas. I think we’ve seen a fair number of examples by now, especially in the realm of mathematics, of LLMs producing these novel ideas. I’d imagine Lee Se-dol would agree.
We haven't seen that in software development though. Chris Lattner, inventor of the Swift programming language recently took a look at a compiler entirely written by Claude AI. Lattner found nothing innovative in the code generated by AI [1]. And this is why humans will be needed to advance the state of the art.
