One of the things I valued in the C++ community is the idea of expressing underlying complexity more explicitly through language / API constructs to help steer people in the right direction (Pit of Success type of stuff). I feel like Rust is taking that further and helping show how nasty most of our GUI (at least) architectures are.
I eagerly watch the progress of GUIs and other architectural work in Rust because they are helping to raise the popularity of solutions we've been ignoring because things have been "good enough".
I'm speaking of more traditional GUI architecture where everything is a bidirectional graph of statically defined widgets. From my understanding, Elm and react style GUIs are some of the models people are looking to in Rust.
