people are impressed because you never need to do leetcode hard problems in any business anywhere in your career to make a few billion dollars. I would fire anybody using company time trying to reinvent some academic search thing instead of just using the hashmap.

Reimplementing quicksort in a language the rest of the company doesn't use in a part of the software that no one ever touches is fireable, sure, but I suspect that on the way to ChatGPT there were more than a couple "Leedcode hard"-grade problems that OpenAI engineers and PhDs solved because the library for that didn't exist before.
