I'm starting to think that the rather slow nature of Claude Code is a feature. In fact if they suddenly sped things up by 10X, I would want an option to slow it back down. Sometimes I am fine with it working unsupervised while I empty the dishwasher or take a shower, but a lot of the time I watch it work. Not only does this help me stop it from going down rabbit holes / chewing through all of my Opus usage cap, but I have a much better understanding of what it's built, in the same way I might if I was pair-programming with someone and they were driving.

The idea of having multiple instances working in parallel sounds like a nightmare to me. I find this technology works best when it is guided, ideally in real time.
