Think of it like this: jumping in a Mario game is very simple. You hit a button, Mario jumps. But once you know how to jump, you can use this ability to jump over gaps, jump on top of bricks, kill enemies, destroy bricks, hit coins out of coin bricks, get mushrooms, jump on top of flagpoles to get points, and much more. Learning one simple thing unlocks a very deep array of options. These are the kinds of features you want in your application.

- Lukas Mathis

This brings to mind a number of different analogues, but none of them fully capture what Lukas is saying: composable functions, rule-based systems - we can say "what is the simplest set of orthogonal abstractions that will enable all the desired outcomes" but that fails to capture the joyful feeling you get watching your character bounce across the screen, which even spreadsheets should in their own way aspire to.
