Not really: ASM.js became WASM. What killed the possibility of WASM being The One Way to run everything is AI... the one wildcard that Gard Bernhardt didn't predict.

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
