Our brainwave activity can be monitored and modified by neurotechnology. Devices with electrodes placed on the head can record neural signals from the brain and apply low electric current to modulate them. These “wearables” are finding traction not only with consumers who want to track and improve their mental wellness but with companies, governments and militaries for all sorts of other uses. Meanwhile, firms such as Elon Musk’s Neuralink are working on next-generation brain implants that could do the same thing, only with far greater power. While the initial use may be to help people with paralysis to type, the grand idea is for augmentation to be available to all. Nita Farahany, a professor of law and philosophy at Duke University who studies the ethical, legal and social ramifications of emerging technologies, is sounding the alarm.
Technology that can read our minds sounds terrifying. But it is also way ahead of where things are. Aren’t you jumping the gun?
I don’t think so and, furthermore, we dismiss it at our peril. While the technology can’t literally read our complex thoughts, there are at least some parts of our brain activity that can be decoded. There have been big improvements in the electrodes and in training algorithms to find associations using large datasets and AI. More can be done than people think. There are a lot of real-world applications and major tech companies like Meta are investing in it.
