Are mind reading technologies--recording dreams and watching them like movies, telepathy, and the like--mind invasion? Should we welcome these types of technologies as part of the evolution of making our lives more convenient? Or are they an ominous development toward an Orwellian future? Nothing spells "Thought Police" quite like mind-reading.
In The Future of the Mind, Michio Kaku explains how these advancements are enhancing our lives. Stephen Hawking, for example, has lost the use of his hands. But a chip in his glasses reads his brainwaves and allows him to control his laptop to communicate with the world.
Mind reading technologies are of course exciting, and will become a part of our lives in the not too distant future. But like all technology, it's only as good or as evil as those who use it.
