Well, that's based on a guess that for every Python programmer you see
talking on the Internet, on Stackoverflow, Usenet, etc. there are probably
ten or so who are invisible to us. They work a nominally 9 to 5 government
or corporate job programming in Python, are forbidden to install packages
which aren't approved by IT, and don't even have access to Stackoverflow
let alone have time to chew the fat here. Those folks, I expect, are almost
all using Python 2.6 or 2.7, with a small minority on even older versions.

Some small percentage of them will still be using Python 2 in 20 years time,
just as there are a small minority of people still using Python 1.5 today.

I'm not sure, I'm not actively involved in that specific project. All I know
is that the guys are always complaining about Jessie, and that they're
using 2.6.
