To be honest, with how bad a target WASM is for any existing compiler, I feel like what killed that possibility was WASM itself.

Its IR design is horrendeous.

Can you talk more? I've seen people say only good things about wasm

Not op, but I only know it as the 32-bit single-threaded binary replacement for JavaScript that can't interact with anything naturally yet people get all excited about when they manage to turn their LLVM slop output into it.

Maybe we've been reading different HN submissions.

That was only the MVP.

Wasm nowadays is 64 bits (except for Safari, the IE6 of our time) and has threads.

True about the wasm inability to call JS APIs with no overhead. This sucks
