Firefox OS

What is the fuzz? We don't need x86 and C++ anymore?

You still need C++ to build the infrastructure (Gecko/Firefox) and C/ASM for the kernel of the OS itself.

And the whole "write applications in HTML" is dangerous, because it attracts shit programmers without any clue about what performance and responsiveness means. Imagine all the shit PHP EXPERT PROGRAMMERS writing all the applications you use daily.

Nothing good can come of saying "fuck you" to the experienced, good C/C++/whatever native code programmers.
