I read the post to see how you would answer, not because I was unclear about what the answer would be, because the only possible answer here is “sometimes.” I especially like the point that Rust can be faster because it enables you to write different things. As I never tire of getting downvoted for saying, I’ve improved the speed of a program by replacing C with Python, because nobody could figure out how to write the right thing in C. If even Python can do this, it must apply to just about every pair of languages.
