Maybe that's true and maybe it's not. Unlike COBOL, Python 2 isn't inferior to its putative successor. Maybe people will eventually move anyway. Maybe they won't. Maybe they will, but not until after we are all dead. Or maybe somebody will say bugger this for a game of soldiers, take the current Python 2, add such features from 3 as can be backported without breaking compatibility and release it as Python 4, and everyone will move to that and forget about Python 3 altogether. I don't know that will happen, of course, but I don't know it won't either. Prediction is hard, especially about the future.
