From personal experience, yes you actually will. Speeding up small pieces of a design that's been in your head perhaps literally for years, is an incredible motivator. So is having a "pair programmer" to bounce ideas off of, 24/7 on demand.

I agree with the sibling comment: the difficulty [now, but also before] is finishing.

the threshold to start is definitely lowered now. So i disagree strongly.

However you can set up loops where the AI do improving by themselves and you just have to steer

I disagree. There are things which are very annoying outside of core ideas or otherwise take a lot of time. Too much time and energy to justify normally. Personal example: https://github.com/wiwa/gpu-typing

Typechecking with my own algorithm. Simple enough to specify in Python. Annoying with much boilerplate in CUDA. Similarly annoying to test.
