Who are you making software for? That matters.

General public? Yeah, assume idiotic.

Developers? If you can't read docs then you can't do your job.

I don't have much confidence in LLMs replacing devs, but if the dev is so arrogant that they think they're too good for documentation and if they have to read is too complicated, then yeah I believe AI can already replace that person. They were just a warm body, not a dev.
