Don't buy it. A sandbox is a sandbox. Yes, javascript runs in a sandbox, but other technologies exist beyond javascript-in-a-sandbox.

This is just really inefficient: VM in WASM in javascript in a sandbox in a browser, is insane and will forever be slow due to complexity.

Fun for the lulz, but for the planet's sake I hope this doesn't get adopted.

Wasm is not implemented "in JavaScript", rather JS engines reuse important parts of their compilation pipeline to generate good code for Wasm.
