I can say I feel that flow state sometimes when it all works but I certainly don't when it doesn't work.

The other day I was making changes to some CSS that I partially understood.

Without an LLM I would looked at the 50+ CSS spec documents and the 97% wrong answers on Stack Overflow and all the splogs and would have bumbled around and tried a lot of things and gotten it to work in the end and not really understood why and experienced a lot of stress.

As it was I had a conversation with Junie about "I observe ... why does it work this way?", "Should I do A or do B?", "What if I did C?" and came to understand the situation 100% and wrote a few lines of code by hand that did the right thing. After that I could have switched it to Code mode and said "Make it so!" but it was easy when I understood it. And the experience was not stressful at all.
