On transitioning from Pyhon 2.7.x to 3.x

As someone who is just starting to move into using Python extensively it is a bit disconcerting and maybe even bordering on confusing to see that the language seems to be stuck in this 2.7.x era.

The only sane decision seems to be to avoid 3.x and join all those who seem to be doing the same. Everything I see out there is 2.7.x -based: books, tutorials, online courses, frameworks, libraries, OSS, etc. In that context it is only smart to stick with the older version.

Because of this, looking mostly from the outside, it seems virtually impossible to imagine Python making a mass transition to the "next generation". I'm sure I'm wrong. I am far from being an expert in the language and it's related ecosystem at this point. I must be missing something fundamental in helping me understand this issue.

What say you?
