Ive always thought an under appreciated point in this story is the word “machine”. A function doesn’t mean anything to a kid, but a machine is so easy to visualize and understand. I’d imagine that with calling it a function “machine” it would be much harder to understand, since you can’t imagine a factory doing work to an input to get an output with the word machine.
