> Python is by most measures the most popular language and became so AFTER that switch

The switch had nothing to do with Python's rise in popularity though, it was because of NumPy and later PyTorch being adopted by data scientist and later machine learning tasks that themselves became very popular. Python's popularity rose alongside those.

> There is no reason for anyone to be complaining about it being too hard to upgrade in 2026

The "complaints" are about unnecessary and pointless breakage, that was very difficult for many codebases to upgrade for years. That by now most of these codebases have been either abandoned, upgraded or decided to stick with Python2 until the end of time doesn't mean these pains didn't happen nor that the language's developers inflicting them to their users were a good idea because some largely unrelated external factors made the language popular several years later.

In case people have forgotten: python 3.3 through 3.5 (and 3.6 I think) each had to reintroduce something that was removed to make the upgrade easier. Jumping from 2.7 to 3.3 (or higher depending on what you needed) was the recommended route because of this, it was less work than going to 3.0, 3.1, or 3.2

You don't realise it but you have actually made my point. People are acting like was a suicidal, harmful move that fucked over Python and ... it didn't matter because Python went on to become insanely popular. Particularly hilarious is that some people have tried to argue that Perl somehow did it better.

In the end your Python 2 project was either worth porting and you did it, or it wasn't worth it and you didn't. Python has gone on to be an undeniable success and it is nearly unthinkable that anyone would use Python 2 for anything. It is absolutely fucking insane for people to still be whining about this in this day and age
