For now my idea is to make such device which could take pictures from our brain and output it on the colorful display. Yeah, setting up an exact time in such device of what happened with us in one or other moment would be very fantastic. But just image that it could be very helpful for example for judgement to recognize which suspected is a really criminal. So no need in material evidences or lawyers, and to pay them to prove that you are not that person who the law is looking for. It would be really great. Sure, our social life would be cardinal different. Therefore, our life could be more confident and easy-tempered I suppose.
