Call me old school but for me direction in which GWT 3.0 is going is strange - if I'm forced to use HTML5/JavaScript libraries instead GWT widgets why I should do anything in Java in the first place - just grab Angular or Ember and be done - GWT doesn't help me too much with server side code anyway. The whole purpose of using GWT/GWTP was to avoid to deal with JavaScript, at least in my case.

You fooled yourself (but you're not alone). The whole purpose of GWT has always been about tooling: http://www.gwtproject.org/makinggwtbetter.html

Now that tooling is quite good in the JS world, GWT is turning to… tooling, still (because tooling for a statically-typed language is different from / can go farther than for a dynamically-typed one), and sharing code.

 

For me TeaVM has completely different approach to the problem than GWT - it allows language agnostic web application development (I never liked GWT no prisoners taken approach - Java or nothing - but as you know there was nothing better in "dark ages" of web application development)  - even that end result is very similar - JavaScript code running in the browser.

I wonder if something similar like Java Byte Code to JavaScript could be done with Microsoft CLI to JavScript (just wild shot - I'm not too familiar with the whole .Net infrastructure - different programming environment)

Not only can it be done, but has been done, many times, including by Microsoft themselves: https://en.wikipedia.org/wiki/Microsoft_Live_Labs_Volta http://jscriptsuite.com/ http://jsil.org/ http://jsc.sourceforge.net/ https://github.com/Reactive-Extensions/IL2JS https://github.com/mtenpow/xaeios

BTW, there are / has been also many source-to-source compilers using C# as input: http://bridge.net/ http://duoco.de/ http://sharpkit.net/ and the pioneer of them all and now apparently defunct: https://github.com/nikhilk/scriptsharp
