So, how is this different from the JVM?

Primarily, there will be no need to download and install a plugin. That, simple though it may seem, was the death of the JVM. Additionally, though I am not certain, I imagine that wasm will have no more access to the host system than JavaScript gets. So it will still be crippled when it comes to working with the things that matter most to people — their local data, large content, etc. The JVM was always able to get more intimate with the system. I’m personally on the fence over whether we should just take the plunge and give web apps full access in order to enable awesome things like a web app that manages a music collection on a local network (without requiring the installation of a server) or continue aggressive sandboxing to protect ourselves from the proliferation of destructive malware, accepting severe limitations in possible functionality as a tradeoff.
