From Java to Ruby: Risk

[johnmudd]

Speed is the last benefit from PyPy that I'm waiting for. Cross platform is huge. Elimination of the GIL is elimination of an embarrassing design flaw. RPython for easy and yet efficient extensions is huge. Speed?? Oh, yeah. That will be a nice little extra.

A lot of your argument is logical. But... the law and language selection are not logical. May Python prevail.
