I'm at PyCon and just heard an interesting keynote from one of the guys with the One-Laptop-Per-Child project. Except for the kernel (Linux) and a few other bits, all of the software for the laptops is written in Python. Including the filesystem. The idea is that kids should be able to tinker with all of the software on the laptop.
The laptop even has a "View Source" button that will show the source code for whatever application is in use at the moment.
In around 10 years, there may be millions of Python programmers in third-world countries.
