Seeing how that kid went about that problem, seeing how interested he seems, makes me want to teach. It's impressive how natural the discussion was with the kid, the two were on exactly the same page throughout the entire discussion. This video doesn't really show that all kids can get this interested in math, but it does show that for the right kids, of which I suspect there are a substantial number, we can be teaching concepts much much earlier.
