I think it massively depends on what your job is. I know quite a lot of people at work use AI to to draft out documents, it's a good way to get started. I also suspect that quite a lot of documents are 100% AI since we have a lot of stuff that we write but no one ever reads, so what's the point in putting effort in?

I tried to use it to write some documentation for various processes at work but the AI doesn't know about our processes and I couldn't figure out a way to tell it about our processes and so it either missed steps or just made stuff up so for me it's not really useful.

So it works as long as you don't need anything too custom. But then we have engineers that go out to businesses and presumably they don't use AI for anything because there's nothing it can do that would be useful for them.

So right there in one business you have three groups of people, people who use AI a lot, people who've tried to use AI and don't find it useful, and people who basically have no use for AI.
