The "time dialation" is real. I mostly manage these days, yet my fun projects progress faster than they ever have, because I can prompt in the 2 minutes between meetings, and come back to significant progress.
Yes, it's not faster to develop with AI if you watch it work. It's faster to develop with AI if you parallelize. Typing was never the bottleneck, but is is a now-parallelizeable part of the pipeline.
Indeed, I hit the stop button quite a bit when Claude goes off course. Then make a note of the right choice so maybe it won't do that again, revert and proceed. I have the feeling there is an optimal size of project proportional to the context size, where you can fit the critical design points into the context and/or there are enough examples in the code of how things should be done.
