The Case Against Python 3

[rampage101]

He's talking as if Python 3 and 2 are completely different languages.

This part is incredibly ignorant: "Currently you cannot run Python 2 inside the Python 3 virtual machine. Since I cannot, that means Python 3 is not Turing Complete and should not be used by anyone."

This part is incredibly ignorant. Turing completeness can not be proved by any language, because to do so you need to provide all possible Turing machines to it and show they can be read.

Also, I don't get the point of why you need to run Python 2 inside of the Python 3 virtual machine... there does not seem to be many use cases for that.
