I disagree. First, Python 2 is actually good. I see this sentiment a lot: because there is 2 and 3 people have a hard time figuring out which one to use. I am hoping that in 2016 we'll finally have full support for Python 3 in all major libraries. Python 3 is a pleasure to use. It's a strict upgrade over Python 2, fixing some long standing warts. I needed to happen, and it is backwards incompatible because it fixes some fundamental flaws. I don't care about the Python3 politics and technological churn, because at its core it's a language that just works. Now, I don't know where PyPy fits with all of this. I haven't had an opportunity to use it for anything. Or rather, Python 2 has not failed me in such a way as to require me to go seeking PyPy. But I am glad for its existence, because once it is usable for the general purpose case, I look forward to not having to deal with the GIL, and having somewhat better concurrency model.
