I don't see a complaint, just an analysis of things that make code slow. Assuming that PyPy will just fix the problem is unrealistic, considering PyPy's limitations (doesn't support every architecture Python supports, lags behind a Python major minor version or two, etc.) Python is a great language and PyPy a great tool, but let's not become complacent or - worse - dismiss valid information just because we like them..
