Nobody ever claimed it was new. It wasn't new when Java tried it.
And the actual Web-Assembly developers don't ignore that stuff. And even if they did so what? Re-inventing the wheel is common and sometimes something good and new comes out of it.
And it's not like Java is in the browser and WebAssembly is trying to reimplement something that's already available. Java got kicked to the curb and for a reason. If it's such a superior solution go ahead and put it back and show all the people working on WebAssembly what a waste of time it is.
Nah, I appreciate the wonderfull work of those WebAssembly people that allowed me to have Java applets, Flash and Silverligh running again in the browser.
Please show me text by actual core developers that claim something is 100% new that isn't. And I'm not talking about some random articles you find with googling.
So really you have no evidece at all, you are just generally angry at everybody who is involved with WebAssembly because they don't site your work and that makes you bitter. Got it.
