Think of it this way: if your problem can be solved by an LLM with the same quality, then it's not a problem worthy of a human to tackle. It probably never was in the first place, we just didn't knew.
The only exception here is learning (solving a solved problem so you can internalize it).
There are tons of problems that LLMs can't tackle. I chose two of those (polyglot programs, already worked on them before AI) and bootstrapping from source (AI can't even understand what the problem is). The progress I can get on those areas is not improved by using LLMs, and it feels good. I am sure there are many more of such problems out there.
