I don't think it's unrelated. Despite the name, WASM isn't really a "web technology" - it's a sandbox technology and a compile-once-run-everywhere technology, and there has always been demand for that outside the web, even before the web existed. It might be that the web is what created enough demand for it to happen in the end, but what do we care?

The problem with JS was never that it's a web technology. It's that it's a bad technology that happened to be in the wrong place at the wrong time to get a first mover advantage.
