Technology doesn't need to be a puzzle.
The future is within touching distance withh EE confirming that their 5G rollout could be available in late 2019. The general expectation is that 5G will be a reality for most of the UK by the mid 2020's. What will this mean in reality? A 5G connection will allow you to download a full HD movie in 10 seconds, 4G would take 10 minutes. More significant is that this brings into reality driverless cars, drone delivery, a true Internet of Things with the ability to connect to all sorts of devices wherever you are. This will herald a new technology revolution with consequences we can only guess at
