> “With an iterative process, the computer doesn't need to use up resources for each iteration. If you know a bit about programming, you might have expected that each iterative call, like each recursive call, would consume a small amount of memory and eventually run out.

Yes, getting recursion right is old hat. But the fact that it was solved a long time ago doesn't mean it's solved for me today. If I program like that in my day job in 2020, I do in fact "consume a small amount of memory and eventually run out"
