> I see Rust as the big next step for the web—a language that is still a pleasure to develop in, but with excellent static typing and tight, targeted builds without the bloat and buildup I'm accustomed to seeing with current transpile-to-JS strategies.

I think this will depend on the output size of the compiled file. I've always gotten very large js files out of emscripten, which are fine for games or media decoders, but would be undesirable for (e.g.) a vdom implementation that's part of a larger framework.
