I see these sort of things, and always chuckle to myself. It's reassuring to see even the Giants screwing up too. It's way too easy to assume devs at some fancy wiz-bang company are all 10X'ers and produce perfect elegant code every time.

Then you realize developers at all companies are nearly universally bad.

It's a kind of miracle any of this stuff works at all, despite all the intelligence that's gone into them.
