I just watched and was blown away by Mary Lou Jepsen's Ted Talk about the experimental work they've been working on to bring out mental imagery to a computer screen. It is very promising to see how close to perfection they are. Her proposal about using stronger magnets rather than larger magnets and utilizing complex magnetic field patterns to construct clearer images from our minds is absolutely brilliant! It is worth considering her questions and the implications of the potential answers:
"Could you imagine if we could leapfrog language and communicate directly with human thought?" "How would we deal with unfiltered human thoughts?"
