 Yeah, I love talking about linear versus nonlinear. One of the first things I do when I talk at war colleges or at military schools is I'm normally asked to talk about complexity and talk about complexity in war. And so when you say, hey, war is complex, right? Everyone will nod their head, whether it's a bunch of cadets, it's a bunch of sergeants, or it's a bunch of generals. And they'll be like, oh, yeah, of course, of course, of course. And you say, all right, well, what do you mean by complex? What does that mean?
