Everyone runs out of steam when it comes to WebAssembly. I used to wonder in the past why we hear so little about it, until I realised that nobody is really using it. Granted, there are those who use WebAssembly, but if we compare it to HTML, CSS, JavaScript, then WebAssembly is simply not existing anywhere near that level. After soon-to-be 10 years, that is very disappointing.
Plenty of people are using Webassembly. Many more will use it once GC is properly supported and you don't need a JavaScript shim layer.
Why does it make sense to compare it to HTML, CSS and JavaScript?
You could say "Granted, there are those who use the webcam capture API, but if we compare it to HTML, CSS, JavaScript, then the webcam capture API is simply not existing anywhere near that level."
Like how not every website needs to use a webcam, not every website needs to port existing code to the web or accelerate heavy computation, which is what WASM is meant for... that doesn't mean it's not useful for ones that do. It's not supposed to replace any of HTML/CSS/JS
