A rock star academic explores the final frontier of personal privacy: your mind. Imagine a world where your brain can be interrogated to learn your political beliefs, thought crimes are punishable by law, and your own feelings can be used against you. Where perfumers create customized fragrances to perfectly suit your emotions, and social media titans bypass your conscious mind to hook you to their products. 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 of the above 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 severely threaten our fundamental human rights to privacy, freedom of thought, and self-determination. Companies, governments, and militaries are all in: from contemplative neuroscience to consumer-based EEG technology, there have never been more ways to hack and track our brains. But access is just the beginning. Our brains can be changed with performance-boosting drugs, electrical stimulation, and even surgical interventions. Soon neuro-cinema, neuro-monitoring, and even cognitive warfare will be commonplace—the brain is the next battleground for humanity. The Battle for Your Brain by Nita A. Farahany dives deeply into the promises and perils of the coming dawn of brain access and alteration. Written by one of the world’s foremost experts on neuroscience as it intersects with law and ethics, this highly original book offers a pathway forward to navigate the complex ethical dilemmas that neurotechnology presents, which will fundamentally impact our freedom to understand, shape, and define ourselves.
