I use ai as I program every day and I find it useful. I also use it for tech support for myself and my home server. The other day I used it to make some changes in my server and I felt like I accomplished tons. But when I thought about it in the evening I realized I could have got it done with less time if I had just read some documents - the ai advice was often out-of-date and I notice that while programming too - for example, I use the spring-ai framework which has changed massively between versions and the ai always gives old advice....

So on average I would say I'm getting about as much work done now as before ai.
