Personal experience, I think. People still complain about python 2.7 even though python 3 has been around for 15 years and python 2 was EOL 3 years ago.
*the choice would be Cobol for most folks, but not only cobol isnt dead, it actually changes and deprecates stuff throughout the years - ex. Cobol77 vs cobol85.
Eh... pip+pypi killing support for python2 is kind of a big problem for continuing to use it unless you have zero external dependencies.
