Wouldn't that be like a calculator saying 'pull out a math book' when you try running calculations?
I tell the LLM what to do in its loop. It builds it. I tweak it until it is perfect. I care a lot about UI.
I'm mostly building my own UIs lately, but I find no problem with the development loop. I'm building much better UIs, because it's way easier to test things, and scrap things that I thought would work, but don't. It all happens in a matter of minutes.
Humans should use more llms.
