It really depends on what kind and of job you do.

If it's not something very common LLMs could end up generating random code.

Also if you work on something performance critical, you can get inspiration from LLMs, but they often don't write fast code.

AI can generate code much much faster.

But do you never need a specific change (e.g. bugfix), that even describing in English is slower than just doing it? Especially in vim where editor movements are fast.

You're forgetting to count the time you spend deleting the excess stuff

Note you're replying to a guy who never said anything at all about being "faster".

P.S. Software developers aren't being paid to be "fast". In fact, being "fast" is called "technical debt" and you're usually punished for it as a software developer.
