It's strange that on the Kotlin side the author goes out of their way to show 'shorter' ways to do things that are also available in Swift but not illustrated.

    let sorted = [1, 3, 6].sorted()
    let sum = [1, 3. 6].reduce(0, +)

as examples

Why are you citing an FP comp Sci professor? I must've missed something

[agumonkey]

seeing reduce in swift made me think about the universality of fold, which is the paper linked.

Ah, was about to say that all goes back to lambda calculus by Church and could be found in Lisp probably around ~1958.

Actually I think there's a relation with exponentials and integral calculus. Or anything hyper-iteration related.
