What if you don't care about the version of python, but you have a bunch of code that runs on 2.7. You don't get anything from moving to 3, you have to learn the new syntax features (friction), you need to upgrade all you code (friction) and some of the libraries you used before don't work and need fixing (friction). If you don't use asyncio, and you already had venv working, what do you gain?
For someone to whom python is just a fancy pipe-wrench, why keep up with the new shiny?
You are right. Just like we should all just be using Word 97 on Windows 95 because, you know, word processing is just word processing in the end, isn't it?
I take it you don't remember the Office 2000 -> 2003 upgrade debacle and peoples unwillingness to just get on board. Most people I know simply skipped 2003 and only reluctantly hopped to 2007 after much gnashing of teeth. I still know a handful of people still using Word 2000.
