I think that we first come to admit ad it's still proving quite difficult, perhaps for control reasons and perhaps for identity reasons. Most of the reasons or things that you think are going to work won't work, because you cannot manage a complex adaptive system from down. I have this vision of them basically ling like, o ga, it's rainy in chicago to day. That means the nikais going to go up point two af a percent. But i not because it's a furious correlation, but basically, sthey've found a butterfly, and their astrophysicists have managed to determine that that is actually the causal link. Is just that we haven't found it yet
