I have to make new things pretty often. If you step outside of the high-level cloud/webdev stuff that most people seem to be obsessed with these days, there are a lot of non-trivial problems being solved in lower-level software such as device drivers, kernels, and compilers.

EDIT: i misinterpreted what you were saying, initially i thought you were asking how i make new things, not how often i make new things. my original reply is below.

weelll, i think about it real hard and do research? Not sure what your point is, but I definitely don't solve these problems by trying to find somebody else's solution to copy, or just dumping a bunch of C code that doesn't do anything and calling it a day like GPT would.
