I have learned to embrace polyglot programming instead of trying to use the same language for every possible scenario.

Personally I see this language X is better than Y at Z a waste of time, because I would just use X and Y depending on what I have to do.

In general I would agree, but a significant part of Clojure's appeal is that it's immutable by default, because that allows you to make certain assumptions about the codebase. Introducing mutable datastructures means you can no longer make those assumptions, so it potentially has much wider ramifications than e.g. calling into C code from Python.
