Turning brain activity to text with AI: Time for nations to debate what is ethical, and what isn't

A few years ago, when researchers successfully demonstrated the use of augmented reality (AR) to treat PTSD by examining which parts of the brain it impacted, no one would have thought that scientists would be able to able to use artificial intelligence (AI) to turn brain activity to text. According to The Guardian, scientists at the University of California (UC) have been able to do so using electrode arrays implanted in the brain. Although the results are not too revolutionary, and AI commits mistakes more often than not, the fact that this is now possible is an achievement in itself. While, in the AR experiment, scientists were looking at which part of the brain gets impacted by certain images and videos to decode neural response, in the UC experiment, AI converted brain activity to numbers related to aspects of speech. The AI, with great difficulty, could only do this for the 50 sentences in which it was trained.
