I've been out of web dev for a while now and forgot these people exist. Why would you even compare framework with a language? Why would you want an AI to build a custom web framework around Rust? Why would you want to never read the code AI writes? It's infinitely easier for me to have a conversation with AI about something I know and understand.

Because it is blazingly and predictably fast with tiny memory footprint.
> Why would you want to never read the code AI writes?
Because it's Rust.

That's why you tell the AI to build (or translate) a framework, rather than the app. Frameworks have shapes you know so it's easier to talk about them with AI.
