Ya, I think it's useful for speeding up personal projects I often don't have the energy for after work, but I want to see the project done at some point still. I've been trying to balance my use of AI on them though, since I think part of the point (at least for me) should be learning new things and keeping my mind sharp, in addition to making the thing. Like, I'll have it find a bug, and then I'll investigate it and try to solve it myself instead of having AI fix it, or things like that.
It's not like work where they don't give a shit about my mind atrophying on over-use of AI and only care about productivity.
