I know that Python will still be obviously superior for, for example, most aspects of scientific computing

That's quite a bold assertion, my friend. I have to say that Python's superiority for that particular field is not obvious to me, if such superiority even exists. I'd be very interested to read how you know this to be true.

I suppose we should also pre-empt the inevitable descent and point out that this comparison has been discussed at some length here before:

• Perl VS Python
• Perl vs Python revisited
• Honest question about Perl, Python and Ruby
• ... and perhaps most similarly Perl and Python
