In the sky, on the roads, and in the home: Robotics and AI in 2018

This story is part of our multi-part series looking at some of the big stories and bright ideas primed to make headlines in 2018. Moore's Law describes the exponential technological progress of computer chips. For the past 50 years, every 18 to 24 months, they have shrunk by about half in both size and cost. This enabled the creation of personal computers and cellphones--two devices that have become ubiquitous, which was unfathomable to the average person just 30 years ago. Rapid progress is being made in many fields, including robotics and artificial intelligence.
