Python3 is about finishing transitions. The last stage in a transition
that replaces something old with something new is to remove the old,
after showing that the new works. I am working on a separate post for
this.) I presume most readers here who are not packrats have at some
time discarded a working machine (perhaps reluctantly) after installing
and testing a new one.
For new learners, not having to also learn the old is a real benefit.
People who already know the old typically do not see that.

I thank you and your group for porting numpy and scipy for the benefit
of those who switch and for new Pythonistas that start with Python3. I
hope and expect that they will eventually outnumber Python2 programmers.
I agree that there may be not much reason to port custom proprietary
apps that are working fine and which would hardly benefit from, let
alone need, and new Py3 features.
