I am pretty AI-skeptic. But I just tried to create a little tool with Junie, and I'm quite in shock. It was SO good I barely had to do anything.
Personally, I still think that they shouldn't be relied upon too heavily, but if you already know what you are doing, some of these tools can definitely give you a big boost.
I am not sure about a "professional" experience. But my personal one is that I had my parents install it on their machine years ago, and since it's running stable and without great changes or weird banner or any other silly stuff that would break the flow.
I can log in remotely and help them. It is also easy to install and run, which is also bonus points.
For me, this smooth experience has been a godsent. When I used TeamViewer I feel like every time I would use it, sometimes months apart, it would break or something would change.
