Yeah, the reason for that is simple: anything else adds (sometimes
massive) overhead. Would you suggest creating a client/server
architecture, a RESTful API, and a triple-redundant HTTPS+SSL+Blowfish
security system, to enumerate files on your hard drive? No, you'd just
use ls(1). In the same way, there's not a lot of point downloading
megs and megs of PyPyJS engine before running a single line of code,
when you could skip that and just write in JS. Before Python can be "a
better alternative", it has to overcome this massive hump.

If Python 3.x were as well supported by web browsers as ECMAScript 5.x
is, I think we'd see a dramatic shift in usage. But it ain't, so we
won't.
