No. While it might be a shame that Python 3 is getting adopted so slowly, Python itself is in no way under fire. They're not the first language to have molasses-like adoption of new versions, and they won't be the last. People most likely stick with Python 2.x because it works, and it's one of the best programming languages for quick prototyping (scripty stuff) ranging to highly optimized stuff (numpy, cython, pypy,etc). R is new and R is cool, but what about D? or what about Go? What about Rust? Whenever I start new projects, I struggle with this, then ultimately go with python because for most things, it's truly "Fast Enough", and many of the higher level concepts that it gently leads you into (generators, lazy evaluation) don't bash you over the head (as much as I like Haskell, it is not an easy thing to learn).
