@22 I understand his argument on the graphics front.
1. The lack of a GUI keeps things down to the brass tacks. If you give a new programmer a GUI they'll play with the GUI and not much else.
2. While JS dominates for client-side scripting in the browser, I think its going to have competition soon. I expect browsers will add Python interpreters soon-ish as MS Office recently did, if I'm not mistaken.
As for standalone executable portability, yeah, that's a weak point. Learn Python, then learn C.
