I have to say that I am a little surprised and disappointed from the fact that nothing seems to be coming out Microsoft regarding WebAssembly.
Perhaps I got the whole WebAssembly concept wrong and it is not that big of a deal. However, the way I understand it so far is that if it comes to fruition, it will basically end up becoming a truly universal CLR. It will first run in the browser but I am sure that soon after it will expand to run everywhere. In other words, it will be the programming infrastructure that will rule all other (aside from niche applications).
This is a huge deal (at least it is to me) and if that is the case, Microsoft needs to seriously start getting involve and give some direction / opinions as best as it can (particularly regarding the role that .NET may play with WebAssembly) There are people right now trying to figure out what to do right now and WebAssembly needs to be part of the conversation…. Just my opinion, maybe I am being too dramatic.
