That last slide kills me: "anything is a sheaf if you want it to be." That's definitely in line with Wolpert's accusation that our SAM may be akin to looking for our keys under the lamp post. But, yes, it's a provocative presentation.

It touches on some of the ideas we have been kicking around regarding Wolpert's paper, on the one hand, and William James ideas about agreement, on the other. The video is pretty accessible for non-specialists. David does a pretty solid job of showing how categories aim to capture perceptions we might have about the world.
