And the real maddening part is that search engines have been so enshitfied to make way for AI that's wrong like 9/10, so you're forced to rely on it for answers because if you try google, the snake wraps around and eats it's own tail giving you an AI answer! 
They do. Most programmers think they're above average (there were actual statistics on this, maybe from stackoverflow survey) and are mediocre enough that they find it useful/faster long term.
I'm statistically likely to be mediocre myself, but I would rather try to improve than relying on LLMs. Every single coworker I work with who is actually above average hates the forced AI usage.
