I have this dream where I'd be able to write an application once in Rust (be it simple game, CRUD, chat, whatever) , target WASM and have users be able to run it (via browser) on desktop, android, or iOS and not have to write the program 4-6 times for different OS's. However - seeing some people diving into the WASM details makes me wonder whether it will be the way the browser implement WebAssembly that stops us from doing something like this, not rust's lack of a GUI framework. So far the best I've seen/read on this topic is this session from a Rust meetup where Azriel Hoh walked an audience through what was involved with porting an existing Rust game to webassembly: https://www.youtube.com/watch?v=7YQGwb4_AvA https://www.youtube.com/watch?v=7YQGwb4_AvA
