Some experts are predicting humans will live in connected underground homes with robot servants in just 20-years.
The experts say each family member will be able to personalize artwork and views from windows using smart glasses, while workers will see video calls replaced with hologram versions of their colleagues sitting next to them. And drones will also fly around homes to keep an eye on children, pass messages to people and monitor the temperature and air quality. The experts also predict pets will keep pets company by entertaining and even feeding them when owners are not at home.
