Just recently I've compiled my side-project Rust game engine to WASM and it runs beautifully in the browser, as well as SSH2 to have a fully featured SSH implementation in the browser over a websocket transport.

It can obviously do amazing things, but the expectation for it to do replace webdev frontend code was always a huge misconception. Though recent developments have made DOM access without a JavaScript translation layer possible, so that might change!

I'd say the hype is still very much alive.
