Chris, there's a big part of me that agrees with you.

However, those millions of servers are running Python 2.6 and a smaller 
number running 2.7. At least in the US market since Red Hat Enterprise 
Linux and its derivatives run 2.6.6 (RHEL 6) or 2.7.5 (RHEL 7). Not sure 
what Python SuSE uses but they seem to have a fairly large European 
footprint. RHEL 7 goes out the active support door (End of Production 
Phase 3) mid-2024.

I've read comments about Python 3 moving from the Zen of Python. I'm a 
"plain and simple" person myself. Complexity to support what CompSci 
folks want, which was used to describe some of the Python 3 changes, 
doesn't help me get work done.

That said, if the next job I go to is 100% Python 3 then I guess I'm 
doing a lot more Python 3.
