Brain-Computer Interfaces (BCI) are a type of direct communication between the human brain and its functions and a computer that allow the human to control an external object, such as an artificial limb, or allow a digital device to control the human brain—for instance, to detect and stop epileptic seizures. A new form of BCI combined with AI is already being used experimentally for emotional therapy in psychiatric patients. I will outline this case and then discuss the ethical problems and possible resolutions that a corporation that makes AI-based appliances might consider in order to enhance the device’s ethicality, marketability, and the company’s reputation.
