AI makes non-invasive mind-reading possible by turning thoughts into text

An AI-based decoder that can translate brain activity into a continuous stream of text has been developed, in a breakthrough that allows a person’s thoughts to be read non-invasively for the first time. The decoder could reconstruct speech with uncanny accuracy while people listened to a story – or even silently imagined one – using only fMRI scan data. Previous language decoding systems have required surgical implants. Large language models – the kind of AI underpinning OpenAI’s ChatGPT ... are able to represent, in numbers, the semantic meaning of speech, allowing the scientists to look at which patterns of neuronal activity corresponded to strings of words with a particular meaning rather than attempting to read out activity word by word. The decoder was personalised and when the model was tested on another person the readout was unintelligible. It was also possible for participants on whom the decoder had been trained to thwart the system, for example by thinking of animals or quietly imagining another story. Jerry Tang, a doctoral student at the University of Texas at Austin and a co-author, said: “We take very seriously the concerns that it could be used for bad purposes and have worked to avoid that. We want to make sure people only use these types of technologies when they want to and that it helps them.” Prof Tim Behrens, a computational neuroscientist ... said it opened up a host of experimental possibilities, including reading thoughts from someone dreaming.
Note: This technology has advanced considerably since Jose Delgado first stopped a charging bull using radio waves in 1965. For more along these lines, see concise summaries of deeply revealing news articles on mind control and the disappearance of privacy from reliable major media sources.
