In the shiny, optimistic vision of the future we will all be living in “smart cities” in which self-driving cars will check the best routes after being charged up on intelligent, connected power grids.
Public services and safety will be carefully managed though data, while devices in our homes will talk to each other and the wider world as part of the “internet-of-things”.
Many of these services will be delivered over what is called 5G. It will be much more than just faster data on our phones, but potentially transformational for our lives – if you believe the hype.
But there is a darker fear as well. What if it is also transformational for our security if we end up reliant on a Chinese company to deliver this future?
