No, definitely not. There are so many programming languages and they are all usable for >90% of all the programming problems out there. So there's significant overlap. Some languages are better: more conducive to popularity; safer; more conducive to not wasting resources; nicer to work with; more expressive. We don't have reliable methods of objectively measuring these metrics, but they do exist. Rust, I believe, has a pretty high aggregate score.
