Thanks for finding the info Terry. It's about what I expected, a typical 
S-shaped adoption curve:

You start with a few early adopters, which takes a long time to grow, but 
once it hits a certain critical mass of popularity, there is a sudden and 
rapid period of growth until the great majority are using the new 
technology.

According to the standard technology adoption life-cycle, we're now in 
the period where the Late Majority are moving to Python 3. By 2020, I 
expect that will be complete, and we'll enter a long period as the 
Laggards slowly convert over a period of about five years.

So I expect that by 2025, the percentage of people using 2.x will drop 
below 1% and by 2030 the numbers using 2.x will be about the same as 
those using 1.x.
