I feel like Angulars 2 is the 3 of Python

I don't see any similarity. Angular 2 is a complete rewrite, while Python versions may have some differences between each other it's basically the same language. I personally think that Python 3 introduced improvements and beginners should start with it. As GVR says, the third version is the future.

@kpenc Now it's finally faster than 2 (3.7, except generators I think), so it's just beautiful.

Guys - it's about the speed the newer version is adopted and not about which is the best ;)

@theZorgEffect well, one of the reasons for slow adopting of py3 was even the speed (was slower than 2, for Python quite important). The first versions didn't even have working backward compatibility in the world where 2.7 was THE interpreter until 3.3 I think?

However, now it's pretty awesome. I just hope they won't come with other breaking version at 3.7, such as... 4.0, motto: let's make it more incompatibile! :D

@KeyWeeUsr well I actually hope they gonna be courageous to break some stuff and here's why: https://youtu.be/qCGofLIzX6g
