speed gets you to have flow though, rather than breaking your concentration with various waits that aren't actually times where you can stop and think because its 7s surrounded by tiring reading.
a milisecond response, that you can then spend 30s focused on is better.
its the same as a build tool. just slow enough build tools really suck, compared to either an instant build or a 30min build
evaluating the areas isnt the same as watching the llm harnes say "thinking" between submitting a request and getting a response
