I think you're being overly pessimistic.  As I said in that post,
getting Python to work well on the CLR requires changes either to the
CLR or to Python (or a lot of work).  None of those are impossible,
though.  I'm still hopeful that someone will solve some of the
optimization problems for Python using type analysis.

Also, Jython shows that even with a performance hit, Python on a VM is a
very useful thing.  So, Python on the CLR could still be useful, even if
it's not as fast as native-python.

In the short term, probably.  Longer term, I think it's up to us, the
various language communities, to see how we can rise to the challenge.
