Stories like this illustrate why I can be so positive about technology. A tetraplegic - unable to niove at all - is able to control a computer with thoughts alone.

"One participant in the study, 'T5,' a 63-year-old man who had never used a BCI before, needed only 37 seconds of calibration time before he could control a computer cursor to reach targets on a screen, just by imagining using his hand to move a joystick." Obviously the technology is some distance away from widespread use. But that it exists at all points the way to a rich future. Image" HPlus.
