Does anyone else feel as if this sort of thing is actually just a giant opportunity? We built all of this stuff in the first place - how can it be so hard to do it again in places that are more resilient to change? It strikes me that we built entire cities like London with far less technology than we have now, we just seem to be mired in politics. It's like the equivalent of trying to repaint a room without taking the furniture out first.
