Facebook Is Funding Brain Experiments to Create a Device That Reads Your Mind

In 2017, Facebook announced that it wanted to create a headband that would let people type at a speed of 100 words per minute, just by thinking.
Now, a little over two years later, the social-media giant is revealing that it has been financing extensive university research on human volunteers.
Today, some of that research was described in a scientific paper from the University of California, San Francisco, where researchers have been developing “speech decoders” able to determine what people are trying to say by analyzing their brain signals.
