Brain-computer interfaces (BCI) aren’t a new idea. Various forms of BCI are already available, from ones that sit on top of your head and measure brain signals to devices that are implanted into your brain tissue. […] But Musk’s plans go beyond this: he wants to use BCIs in a bi-directional capacity, so that plugging in could make us smarter, improve our memory, help with decision-making and eventually provide an extension of the human mind. 2018 January 1, Sarah Marsh, “Neurotechnology, Elon Musk and the goal of human enhancement”, in The Guardian, →ISSN:
A BCI is a device that allows for direct communication between the brain and a machine. Foundational to this technology is the ability to decode neural signals that arise in the brain into commands that can be recognized by the machine. 2019 October 24, Oscar Schwartz, “Mind-reading tech?
