Mind-reading machines are here

Scientists have developed the first non-invasive method of determining the gist of imagined speech, presenting a possible communication outlet for people who cannot talk. The thought-to-speech technology relies on functional magnetic resonance imaging and large language models. Researchers used it to decode imagined speech in volunteers while they listened to podcasts. But the results were hit-and-miss, and it was easy to trick the technology. Neuroethicists are split on whether the latest advance represents a threat to mental privacy.
