<i>&quot;PyPy is not yet the official future of Python.&quot;</i><p>We&#x27;re past that point. PyPy is the future. CPython is the past. The PyPy team  succeeded in making an optimizing compiler for a language that fought them every step of the way with gratuitous hidden dynamism. That&#x27;s a considerable achievement.  It extends the life of Python by making it competitive on speed.<p>Go exists mostly because Python was too slow.  Google used to use Python quite a bit internally, but their effort to speed it up, Unladen Swallow, was a disaster.  That provided some of the motivation for Go.
