Very interesting, I read a bit about it. Up to now, I was mainly watching systems like volt. A bit too cutting edge for me right now, but I love what they're doing. I'm hesitant to make tech predictions, since what usually happens is something you didn't see coming all, but I'm still figuring transpiled ruby/python/whateveryoulike to javascript will emerge.
I'll dig more into webassembly when I get the chance.
That'll probably never catch on. Front end dev already have 10 frameworks and 5 browsers to worry about. Let's not add 10 more languages for a total of 500 different combinations.
