- These technologies are only for people with serious medical conditions. Warwick consistently neglects this important qualification. Upon having used his implant to pilot an electric wheelchair he comments, "I told everyone that this would ultimately mean, in the future, we should be able to drive a car around by picking up signals directly from the brain, and change direction just by thinking about it, right, left, and so on."
