The advice today reflects the great progress that has been made over
many years of migrating projects and organisations to Python 3.

Instead of ‘2to3’, the best advice today is: write new code targeting
Python 3 directly, and only if necessary back-port to Python 2.

> 2.x is not going away as fast as some would like.

Likewise, Python 3 as a primary development target is not as difficult
as some would fear.

Python 2 is unarguably a legacy platform, but it has good support for
receiving code carefully targeting both Python 2 and Python 3. So it's
best to target Python 3 primarily, and back-port code to Python 2 only
as and when needed.
