But that's already possible today without WASM. E.g. there are react plugins that render to canvas, as being used here together with some WebGL: http://www.anagram.paris/ (try to drag). And yet, we don't see this often being used. Instead, we see more DOM being used on new places (e.g. electron applications). I think if WASM+Canvas would be the way forward, we'd have already seen it by now, since it was already possible in plain JS or with asmjs if you really hate JS that much.

In the end, HTML & CSS is fast enough for most business-style applications and frameworks like angular/vue/react are pretty good ways to make frontends.

Yes, but today it requires using JS or compiling into asm.js, which isn't always possible to keep the original language semantics.

WebAssembly is just yet another virtual CPU. more suitable as target for Go, .NET, Java, Flash, ....

They only need to target the framebuffer routines into Canvas/WebGL and we get desktop frameworks inside of a browser frame.
