Neema Aggarwal Posted 11 months ago Will mind-reading eventually become a reality and what are the implications for humanity? Hi Lauren, The question you posed is both incredibly fascinating and incredibly horrifying. I personally do feel that as we map out the electrical signals in the brain and gather data on how the different signals are interpreted, we come closer to “reading people’s brains”. But at the same time, we do still have a long way to go. I would imagine we will start from just basic interpretation of what kind of emotions a person is feeling, happy, sad, angry, confused, etc… I say basic but of course this would be a feat of its own considering how complex emotions can be and how they manifest differently in each individual. Understanding exactly what a person is thinking is still far away, but I believe it could happen. That being said, it is interesting to imagine what that could mean for humanity. Used properly, this ability could benefit a lot of people. In terms of medical treatments, helping patients with dementia like you suggested could be very advantageous. It could be used in the justice system to glean truthful information about a case from a suspect or witness. But it could also be highly dangerous. Imagine what it could mean if abused by politicians, terrorists, or corrupt officials. I think we have a long time before such technology can be developed and trusted to exist in our society.
