In the smart home of the future, there should be a robot designed to talk to you. With enough display technology, connectivity, and voice recognition, this human-interface robot or head-of-household robot will serve as a portal to the digital domain.

You're not going to talk to your vacuum cleaning robot: in fact, you may never see your vacuum cleaning robot because, ideally, you come home every day and your floors are freshly vacuumed.

It's going to be interesting to see how society deals with artificial intelligence, but it will definitely be cool.

The reason it has taken so long for the robotics industry to move forward is because people keep trying to make something that is cool but difficult to achieve rather than trying to find solutions to actual human problems. Technology can be extremely expensive if you don't focus.
