My field is data science in a highly specialized technical environment. I use AI quite a bit now - mostly as autocomplete while coding, but more and more also for other use cases - help with naming, validating some approaches.
My opinion is that it's great for senior guys, horrible for younger ones. If you know what can go wrong, you can use it the right way. As a junior, you usually don't and in the long term you will loose a lot of time and develop much less skills with AI.
I don't see it replacing people in my field anytime soon, if ever. I do see it replacing a lot of people in say web programming, in the same way that most people don't need to do their website now because they can just use a service like Wix. For anything non-trivial, there is 0 chance that AI will work within the next 5 years.
In the end, it's just a tool. You still need people to know what to do, the how is usually easier.
