>Writing new code in Python 2 is completely nuts and just makes everyone's life harder (including your own).

And when it makes someone's life harder, they will change. If it's too late for them and affects them, they will have themselves to blame.

This, really, is the only reason for people to change to Python3. Yet people keep evangelizing all its great features, etc as if the existence of a much better language suddenly obligates everyone to switch to it.

It's fine to point out potential repercussions of not switching now. But moralizing it is counterproductive.
