That sounds intimidating. When I started my coding career, I followed my passion. I wanted to advance free software. I wanted it to be less buggy and more user friendly. I had no advantage over an average person in the field, I didn't even have a computer science degree.
If somebody's passion is faster command line tools, let them make a faster ripgrep. First results may be disappointing, but those who don't give up will figure out how to do it right.
I think what the OP is getting at is that if you can only prompt the model and aren't bringing anything to the table yourself, you're going to get a generic answer that looks like all of the others. The point is to figure out what differentiates you as a developer. Yes, that will favor those with more experience, but that's always been the case.
The point is, if you have no more detail in your idea than "faster ripgrep" then you don't contribute anything meaningful. Any number of other people can come up with "faster ripgrep", and the LLM won't respond differently to that prompt just because you're the one issuing it.
