Errrm.... Javascript isn't "also inefficient". Qml is using V8 engine,
which is quite a bit more performant than the Python VM (take your
pick of benchmarks, they're all on the google).

Yeah, and I heard some african guy mention something about a phone, too.

Yes, Python is falling out of favor for performance reasons. But the
issue being asked about here isn't that python is "second-party", it's
that python is "no-party". It's currently *not even possible* to write
a phone app in python.

Of course, python is *on* the phone (convergence!) but currently it's
only possible to write non-graphical applications with it. So you can
use it for system daemons, but not for graphical apps. This is kind of
a strange reversal, because historically you want to write your system
daemons in a more performant language, and leave python for the easy
job of gluing UI widgets together.
