>If you have been around functional programming for a bit, you might see the word “monoid” and “categories” and wonder “oh, is julia writing about monads, like in Haskell”? I am not!!

…I don't think that answers the question.

Monoids don't come from Haskell. You'll see monoids discussed in Haskell plenty, sure, but the math precedes the programming language by at least a few decades.

Probably true, but I know some upper level math through programming, and I associate "monoid" with Haskell and an abstract concept, but "tensor" with tensorflow and a more concrete idea.
