&gt; Having two similar languages on different platforms isn&#x27;t as useful as having the same language on both platforms, though.<p>Sure, but as we&#x27;ve seen from the WebKit&#x2F;Blink fork, Google and Apple aren&#x27;t capable of sharing stewardship of something that central to both of their platforms in the long run. So it&#x27;s not going to happen.<p>iOS and Android both disappoint me as being one-language-dominates platforms; I much prefer the paradigm of Windows, Linux or OS X, where you can have apps in Python, apps in C, apps in VB or Lisp or FORTRAN or Brainfuck, all running as first-class citizens. It feels like a real step back for me.
