A technology analyst has warned that we might not yet be ready for what is known as the Internet of Things. This is the next stage of the digital revolution. It will greatly transform our lives via the interconnectedness of all the devices in our daily life. The technology research company Gartner predicts that by 2020, nearly 26 billion devices will be on the Internet of Things. They will communicate with each other to make decisions a seamless experience. Our fridge will contact the delivery service when it senses we need more milk, and hey presto, the milk arrives.

The ComputerWorld magazine says that the Internet of Things has, "the potential to drive fundamental economic and social change". However, there are "serious obstacles" for the infrastructure to be in place in time. These include building new data storage centres, data storage and management and data security. A cyber-security expert warns of "the law of unintended consequences" with the explosion in the number of connected devices. He predicts that privacy will become a huge worry because of the large number of things in our daily life that will be connected to the Internet.
