If you have ever caught one of my favourite films, Minority Report starring Tom Cruise, you would have caught a glimpse of what futurists imagine the smart cities of tomorrow will look like. It's a display of forward-thinking technology - from gesture-controlled interfaces to 3D holograms to dynamic e-newspapers that can roll up. The movie is set in the year 2054.
That future is getting closer faster than we thought, thanks to the advent of 5G technology. In fact, some of that Minority Report technology may already be here. Think predictive analytics and targeted advertising.
