A new dawn of brain tracking and hacking is coming. Will you be prepared for what comes next? Imagine a world where your brain can be interrogated to learn your political beliefs, your thoughts can be used as evidence of a crime, and your own feelings can be held against you. A world where people who suffer from epilepsy receive alerts moments before a seizure, and the average person can peer into their own mind to eliminate painful memories or cure addictions. Neuroscience has already made all this possible today, and neurotechnology will soon become the “universal controller” for all of our interactions with technology. This can benefit humanity immensely, but without safeguards, it can seriously threaten our fundamental human rights to privacy, freedom of thought, and self-determination. In this interview, I speak to Nita Farahany – widely considered to be one the foremost experts on the ethics of neuroscience. We discuss the battle for our brains – and why we need to defend the right to think freely in the age of neurotechnology.
