Over the next four weeks, BBC News will be offering a snapshot of the day in the life of a city - looking at how technology is transforming our urban landscapes, now and in the future.
We will look at how technology is improving the morning commute, what it is doing to make our working day better, how it will transform our evening's entertainment and what goes on at night in the smart cities that increasingly never sleep.
We start as urban dwellers around the world begin the day - with the morning commute. In the future, that may mean hailing a jetpack [bbc.com].
Futurism is always fun. How would you prefer to get to work, by jetpack, Hyperloop, or VR?
