How Far Has AI Mindreading Come?

It's becoming easier all the time to read signals from the human brain: Tesla founder Elon Musk's company Neuralink just this summer announced that human trials will move forward next year for an implantable device that can read a user's mind; scientists at UCSF recently released the results of a brain activity study, backed by Facebook, that shows it's possible to use brain-wave technology to decode speech; in 2018, Nissan unveiled Brain-to-Vehicle technology that would allow vehicles to interpret signals from the driver's brain; and Nielsen is already using neuroscience to capture nonconscious aspects of consumer decision-making. There will be good and bad outcomes. Recently, we've talked about how high tech can help the blind see and amputees feel by reading brain signals directly. A mind-controlled robotic "arm" can help sufferers from movement disorders with the tasks of daily living. One workplace use is to monitor drowsiness in, for example, the operators of high-speed trains.
