Maybe just to address the first point.... Whether it's sometimes beneficial to have that geographical concentration is what I'm reading into the point that you raised. We think it is useful in many respects to have that economic clustering. I think when you look at it, the performance of firms, of innovation systems, people who are located in a cluster really do benefit from things like lateral movement of people, the development of expertise for the financial system to serve their needs, the development of partnership opportunities, even proximity to competitors. All these things tend to increase the performance of innovative firms. That's not to say that you can't do it without being located in a cluster, because we have all kinds of examples of where that's worked.
