This is an excellent comment. Then I realized you're the same person who wrote the article I currently have open in the next tab. Advice for the next dozen Rust GUIs - https://raphlinus.github.io/rust/gui/2022/07/15/next-dozen-g...

Insightful point about how the struggle to converge on a well-designed UI paradigm is related to a larger question of how the industry is still experimenting and exploring the problem space, particularly:

> reactivity, which is at heart incremental computation

Another comment that caught my attention up-thread was talking about "incremental lambda calculus", which is the same question in different words. My impression was that ideally it needs a language-level solution to be able to support "diff" and "patch" not only on the data but the running code, perhaps built from primitives like continuations.

> feels to me a bit like async

Maybe part of the difficulty with reactive UI is fundamentally related to how the language "solves" async, for which there's still no real concensus on the best way to solve it.
