Yes, it also can matter what you even mean by "competitor." Some people take it to mean "similarity in language features." Others can take it to mean "would I choose it as a substitute." Some take it to mean "would I choose it as a substitute for this specific domain or project."

I've seen this play out a number of times. "Rust cannot compete with C, because C is too entrenched in embedded." "I do embedded development in Rust, so it can." "Well, I work with these chips that Rust can't target yet, so it can't, for me." None of these statements are incorrect, but they can lead to huge back-and-forths.

Words are hard.
