I thought the entire discourse on how important pointing is to be super interesting. I've been told, although I don't know if this is true, that dogs are the only animal that can understand human pointing. Fascinating to think this might be fundamental to world intelligence requirements. Well, it's required, but it's interesting to think that it might be a core structure required or that learning it might force some sort of neural architecture that's helpful.

And, I was disappointed to see that pointing was just giving x,y coords. I wanted to see robots pointing at stuff.
