UIs are inherently about state, and a lot of state is hard in Rust. The big 'tree of state' is just awkward. UIs are inherently async and event drive, it's callbacks over callbacks, again, harder in rust. UIs have a lot of detail. A little screen has a lot of hidden bit of small complexity. Rust is a heavy language that wants to treat every line of code as an existential security threat and performance. It's really not the right tool.
