The Density Matters

I think if you spread it out too much, then you lose almost all of the benefits that you're gaining in the first place. Everything we know about humans indicates that the density matters. Once you get a place that's super specialized, the best people are always going to want to go there. And so I merely think that London could be like the second most important city in the world if it is collecting up all of the smartest ambitious people in the European Union who can easily move there and try to get things started.
