We use Python for web apps and I heard one developer complain that Python is a slow language and asked whether we should consider a faster language ("like PHP").
I just told them that if they find a function in the web application where we are actually bottlenecking on our Python code, I'll personally rewrite that in C (although I might actually just use Rust instead).
No complaints or rewrites thus far. I don't actually think the other developers, including the one lodging the initial compaint, know where our performance bottlenecks are. They just know that "Python is slow" and repeat that.
