While I think the author mischaracterizes the Python community as "afraid of change", there is a strong point in how rapidly the Ruby community--including really big projects like Rails--adopt the latest language release versus similarly large Python projects still not adopting Py3k after 3.5 years.
When working with anything Ruby-based, I hardly ever have to wonder whether or not Package X runs on the latest Ruby. With Python, it's been a somewhat default expectation with any given Package X that it won't run on anything greater than 2.7.
This is rather disappointing because there's so much to like about Python3, and I think it'd be much nicer to know that the community was supporting the latest releases by keeping great software up-to-date with the language.
