When algorithms control the world

There will be no soothing HAL 9000-type voice informing us that our human services are now surplus to requirements. Why web personalisation could skew objectivity. Information we see online is increasingly being tailored by filtered, personalised searches on search engines, automated recommendations from online bookstores and social networks whose algorithms only tell us what is happening to those friends we care about the most.

In fact, he's more than just an advocate of mind-controlled robots; he believes in training them through the power of thought alone. His team at the Neural Systems Laboratory, University of Washington, hopes to take brain-computer interface (BCI) technology to the next level by attempting to teach robots new skills directly via brain signals. Robotic surrogates that offer paralyzed people the freedom to explore their environment, manipulate objects or simply fetch things has been the holy grail of BCI research for a long time.

Dr Rao's team began by programming a humanoid robot with simple behaviours which users could then select with a wearable electroencephalogram (EEG) cap that picked up their brain activity.
