Never before have we had so much data about individuals, about transportation, about the economy, on such a fine-grained level as we do today. We see that as developing into the future, exponentially so. With that we'll be able to build our understanding of the city, and improve our models of the city. The bike data - the bike-hire data - from that we'll be able to identify different types of usage and where they're used, and why. We have the data on the locations of tube trains, of buses, we have oyster card data - so people's movement from origins and destinations across London - with that we're beginning to understand, better than ever before, where people go, when, and why, and start to understand how people change their behaviour in different circumstances. So this is already happening, to a certain degree, and I think in the next 50 years you can imagine that more increasing levels of individual data will become available, so relating to each of us, about our individual behaviours. But at the same time you can imagine there'd be a kick-back against this movement, so as it becomes increasingly known that your financial transactions are available to researchers, what will people's responses be to that, and will they be happy with that sort of research continuing? I think we're really seeing these sort-of patterns of realisation occuring - if you look at organisations or companies like Facebook, there's a small movement there against Facebook their utilisation of people's data for advertising, or marketing purposes, so this is a trend you may see continuing as data increases, as individual data increases and people become aware of what data can be used for. As these data sources become available and more accesible and easier to understand, people will become better at understanding these and being able to use them for their own purposes, to question their government, to make decisions about their own lives.
