I have three very inquisitive kids and I love trying to explain complex topics, like reinforcement learning, to them in a way that they can understand. The best thing I get out of it is clarity for my own understanding, or gaps/lack of clarity, so it's a valuable exercise.

People don't give children enough credit for what they can really understand.

I remember distinctly teaching my oldest daughter how to do a basic cipher - like direct substitution and she got it immediately. I also taught my son how to do pin bumping and pin counting/picking on locks with my lockpick set. I even bought him a transparent set of master locks to practice on and he would sit for an hour at the age of 4 picking those locks. The obvious downside now is that he knows how to get into everything!

Very cool to watch what are basic principals being applied at the very basic level.

Exactly. My 4 year old sometimes surprises me like that. Last week she asked me how you can talk into a mobile phone. So I said, there's a tiny transmitter in there, and it sends the voice over waves in the air. So she's like, "OK" and I thought it went over her head.

Then yesterday she asked: "Why couldn't you call gramps when we were on the plane?" I told her that the mobile phone wasn't close enough to the receivers on the ground.

It amazed me that obviously some facts had been stewing for a week in that tiny head. And out comes another question.
