Understandably, I'm sure there will be a lot of focus on physical and transport infrastructure. I think it would be worth also looking into ways to transform the social infrastructure of a city.

I'm sure most people would agree that cities tend to bring a certain degree of isolation. Once upon a time people would know everyone in their town, but in a large city today it's pretty rare to even know your neighbours.

Of course, in the year 20x6 we have lots of social infrastructure, but mostly it starts with an assumption that you want to choose who you interact with. But what if you shouldn't always choose? In the wake of the Brexit some commentators have rightly asked "how didn't I know anybody voting leave?"

For better or worse, we are stuck in proximity to a certain number of people, maybe people quite different to us. In cities, we tend to ignore that as much as we can, and our social tools follow suit. Could we build new ones that instead embrace this restriction and turn it into a good thing? Could we bring a sense of local community back to our cities? Could we build slightly-out-of-your-comfort-zone-as-a-service and pierce the filter bubble at least a little?

I'm not sure, but I think it's worth finding out!
