I was speaking two languages at two years old, and debating political systems by ten. I'm not really sure that talking is actually that hard, depending on your cultural background. The more diverse, the easier you may find it to convey incredibly complex concepts. I'm not an outlier - I'm a boring statistical point.

I've heard plenty of overly complicated explanations of what a monad is. It's also not a complicated concept. Return a partial binding until all argument slots are filled, then return the result of the function. Jargon gets in the way of simple explanations. Ask a kid to explain something, and it will probably be a hell of a lot clearer.

The more experience you have, the harder it often is to draw out something untainted by that experience to give to someone else. We are the sum of our experience, and so its so darn easy to get lost in that, rather than to speak from where the other person is standing.
