It’s been so easy to consider this piece so deeply because it’s right in front of my face all the time. I can pick it up. It’s physically there. It’s physical presence helps me understand it.

And then I started to think about the things that we create which aren’t physical, and the problems that we tend to face with maintaining, knowing, and understanding those things. Teams of very smart people who spend hours and hours fighting against software systems, for instance, that everyone knows some part of but no one could possibly know in its entirety.
