I think it's very interesting and very important and I also appreciate the historical angle. I've often argued with respect to HCI type topics that there's a lot of embedded knowledge in very old practices. These maps that we're looking at here, these are maps that people created when it was extraordinarily expensive to create a map and or that were preserved over thousands of years were extremely hard to do that and or where the technique was repeated again and again. So there's something worthwhile or working here. Even if we don't initially understand, there's definitely something important to know. And I also think it's useful because we often get some blinders working in digital tools because it's actually a very limited medium. The screen is very small, it's low resolution and so on. And so you can often learn or get ideas for new techniques that become applicable as computers get more advanced if you go back and study these old examples. So definitely worthwhile.

One thing that comes to mind for me is I think the word map for I think most English speakers lead you to thinking about, I guess what we call a geographical or a cartographical map. That is to say what you see when you type maps.google.com into a browser. But one, I think it's interesting that this actually, we think of it as being a very kind of literal map, I guess, but it's actually quite abstract. First of all, it's sort of a projection, right? Taking the surface of a globe and the terrain and all that kind of stuff and flattening it down onto this like two-dimensional thing. But secondly, putting aside, I don't know, satellite photos are going up in a plane. We don't see the world this way, but it seems to be quite natural for many or even most people to look at this kind of bird's eye overhead map. That's actually a pretty abstraction of how things are laid out and then be able to use that to navigate a complex place, which is really quite interesting to me.
