We are totally on the way of smart design of cities. It is not science fiction. If you look for examples of any of this, it's all already underway.

it's never one individual. Far from it. It has to be a critical mass of people who bring their ingenuity, their innovation, their creative thinking and their solution development together. If we're going to do this, it has to be an everyone-in effort. So we went from something that was impossible in 2009 to something that was, OK, maybe possible. Over the years, we moved from possible to likely. And then, eventually, in 2015, to unstoppable. So that arc of possibility is what eventually led to the Paris Agreement.
