Personally I do this as well now with a lot of stuff. I've recently had a lot of issues with my knee, which was operated on about 20 years ago because of a torn cruciate ligament, and now it was acting up again. The specialized doctor did a x-ray (which I thought was pointless because I was sure it was not bones related). Long story short, my left knee is 20 years older then me because of increased knee wear and tear. I don't have a doubt the doctor is right, but I did doubt I memorized everything correctly, and later on I had some more low effort questions I didn't want to bother them with like what movements should I prevent and specifically what training I should be doing at the gym.
Thankfully I got a pretty detailed report that I couldn't read because of all the medical terms. I've fed this to Claude and asked for a human readable conclusion and it repeated pretty much everything the doctor told me, which was great, I now have a readable report for future reference. Secondly I asked it questions about what movements I should and shouldn't do, and it eventually I made a gym plan to improve stability and prevent any more wear and tear in my knee. Lastly I validated this with the assigned physiotherapist, and the plan I created with Claude was perfect!
I probably won't ever use AI as a second opinion, but I would definitely use it to ask numerous silly questions that would help me in day to day life.
