>There idea that we could write programs in our own favorite language, and compile it to a universal format that can executed on almost any platform is truly revolutionary.

Where do I begin with this...

I Think Rust+WASI is cool, but this idea has more years than I do.

Seems to me Rust + WASM is just a recreation of the Java Applet outside of Oracles control.

I guess they forgot Java is Open-Source and anyone can make a Applet plugin if they wish.

The main reason that is not happening is that the browser is dead.

The core use cases of WASI have nothing to do with browsers. Yes, though: Java itself--without applets--also solves mostly the same problem.

I prefer WASM to the JVM

I think the main difference between WASM and JVM is that WASM was designed as a generic compilation target for all kinds of existing languages like C or Swift, while JVM is designed to specifically run Java bytecode with the features that Java-based languages support.
