Brave New Machines
Robots are here to stay. They will be smarter, more versatile, more autonomous, and more like us in many ways. We humans will need to adapt to keep up.
The word “robot” was used for the first time only about 80 years ago, in the play “RUR” by the Czech author Karel Capek. The robots in that book were artificial humans, chemically synthesized using appropriate formulas. Robots at present and in the future will be made largely of inorganic materials, both mechanical and electronic. However, some form of hybridization between electromechanical and biological subsystems is possible and will occur. I believe that the major developments in robotics in the next 100 years will be the following areas:
Robot intelligence: The ability of a robot to solve problems, to learn, to interact with humans and other robots, and related skills are all measures of intelligence. Robots will indeed be increasingly intelligent, because:
- High speed memory, long term storage capacity, and speed of the on-board computers will continue to increase. Futurist Ray Kurzweil has predicted that the capacity of robot brains will exceed that of human brains within the next 20 years.
- Neuroscience is rapidly obtaining better and better models of the information processing ability of the human brain. These models will lead to the development of software to enable robot brains to emulate more and more of the features of the human brain.
- Research in learning will enable robots to learn by imitating humans, from their own mistakes and from their successes.
Human-robot interaction: This is an area of significant research activity at the present time. I believe that during the coming decades robots will be able to interact with humans (and with each other) in increasingly human-like ways, including speech and gestures. Robots will be able to understand the semantic as well as the emotional aspects of speech, so that they will understand the significance of increasing loudness, irritation, affection, and other emotional aspects in spoken utterances, and they will be able to include these aspects in their own speech as well.
