From having read the various replies to this and similar threads, I think a basic problem (as Travis pointed out) is that Fijal has been (1) highly dismissive of numpy and particularly cython, which a lot of really smart people have put a lot of time and effort into and created an amazing scientific community within python, and (2) confrontational with people who are trying to lend an alternative opinion which has been informed by a lot of experience in the scientific python world. PyPy might eventually be a wholly superior alternative for scientific computing with Python, but it would be good to acknowledge the insight of those who are 'in the trenches' even if you go a different route, because part of the success of scientific python has been the community. I know very little about the development aspect of PyPy or Numpy, but I know that at this moment in time Numpy/Scipy/Cython have revolutionized how I do research on a day to day basis. It seems unfortunate that there seems to be such animosity surrounding this issue.
