Most scientific & mathematical disciplines I know of have results that educated outsiders can appreciate and go "wow" after a brief acquaintance, even without understanding the details. Does anyone know of such a result for category theory?

Note the word "brief" here. This request is easily fulfilled for fields ranging from linguistics to algebraic geometry to general relativity to molecular biology. Curious if there is such a result for category theory.

I suspect @johncarlosbaez or @emilyriehl will be able to give a good example or two

Yup, but we've both already spent plenty of time explaining this stuff. Decades in my case.

As you know, I've read a lot of your writing, John - probably hundreds of thousands of words, and I've studied some tens of thousands (esp. yr book with Muniain). But while I tried reading some bits and pieces of your writing about category theory, it never seemed aimed at me.
