It cannot have escaped anyone’s attention that AI is here to stay, is rapidly colonising all aspects of social life, including the law and that, to echo Mark Leiser’s previous book, Dark Patterns, Deceptive Design, and the Law, has a dark side – to say the very least. What is perhaps far less known is how AI is now using data culled, not from what people say or write, but directly from their brains in the form of neurodata. This may have valuable applications in some areas, like medicine, but it is potentially highly problematic in the legal sphere, such as policing and the proof of crimes. Dr Leiser’s new book, Artificial Intelligence, NeuroData, and Society: Law at the Edge of Cognition, presciently explores the implications and possible regulatory solutions to this growing interface between AI and neurodata. It is a must-read for anyone interested in the legal process, AI and Neuroscience.
