alt Hacker NewsThe only failure of WASM is that it was overhyped beyond all reason. It's "just another" virtual instruction set, and for that it turned out pretty great. It's supported by Clang and by all browsers. That's already enough to make the whole idea work.
You don't hear much about it because for the people using it, web+wasm is "just another porting target", like Windows, macOS or Linux. WASM has become 'normal' and that's a good thing.
The main risk these days for WASM is feature creep, the spec is getting bloated with optional features (garbage collection etc...).
I like to think about it as a VM that all the major browsers agreed to implement, designed by a broad group of stake holders with lessons from past plugin and VM systems
For that it's pretty cool. I still wish we had DOM access though
