Appreciate your insights. I don't really have an answer to your question. I respect the popularity factor, I just can't help but think that we've had (and still currently have) competing technologies which are far more mature and capable. Not saying WASM won't end up on top in the future. There are plenty of applications today that build on parallelisation, synchronisation primitives, IO, IPC... all of which are already perfectly possible today over the JRE/JVM (as an example), but the same can't be said about browsers today (no doubt that with enough work, it can all change sometime in the future). Just feels like reinventing the wheel.
