I see is people crying how python is slow and then use a proper fast programming language to write code that gets executed so few times that even if python was 100x slower it wouldn't matter or the program is so trivial that python's speed definitely isn't an issue.
I have even sometimes seen people stop using a tool when they find out they were written in python - now all of a sudden they are unusably slow. Then they try to justify it by writing some loop in their favourite proper fast language and tell me how fast that tight loop is or they claim that some function is X times faster, but when I actually compile it and run something like hyperfine on it and python version the difference is hardly ever X since there is already so much more over head in a real world.
