If it takes 10x the time to do something, did you learn 10x as much? I don't mind repetition, I learned that way for many years and it still works for me. I recently made a short program using ai assist in a domain I was unfamiliar with. I iterated probably 4x. Iterations were based on learning about the domain both from the ai results that worked and researching the parts that either seemed extraneous or wrong. It was fast, and I learned a lot. I would have learned maybe 2x more doing it all from scratch, but I would have taken at least 10x the time and effort to reach the result, because there was no good place to immerse myself. To me, that is still useful learning and I can do it 5x before I have spent the same amount of time.

It comes back to other people's comments about acceptance of the tooling. I don't mind the somewhat messy learning methodology - I can still wind up at a good results quickly, and learn. I don't mind that I have to sort of beat the AI into submission. It reminds me a bit of part lecture, part lab work. I enjoy working out where it failed and why.
