 If you then infer causality that's a neat and tidy story, you actually are learning exactly the wrong lesson. So I think that lesson is that sometimes when bottlenecks happen, it reshapes the trajectory of the future, but it also is inescapably arbitrary at times. And we don't like that. I mean, the entire world of self-help and the entire world of sort of business advice is, oh, these people were successful. Here's how you replicate it. And the replication is always just do what they did, right? But I mean, of course, the world's different now.
