Yeah, my current opinion on this is that AI tools make development harder work . You can get big productivity boosts out of them but you have to be working at the top of your game - I often find I'm mentally exhausted after just a couple of hours.
I have a similar experience. It feels like riding your bike in a higher gear - you can go faster but it will take more effort and you need the potential (stronger legs) to make use of it
You can go further and faster, but you can get to a point where you're out of juice miles from home, and getting back is a chuffing nightmare.
Also, you discover that you're putting on weight and not getting that same buzz you got on your old pushbike.
