Alarm bells aside, this was fascinating: > The decoder produced more accurate results during the tests with audio recordings, compared to the imagined speech, but it was still able to glean some basic details of unspoken thoughts from the brain activity. For instance, when a subject envisioned the sentence “went on a dirt road through a field of wheat and over a stream and by some log buildings,” the decoder produced text that said “he had to walk across a bridge to the other side and a very large building in the distance.” It sounds like it's reading a persons snapshot of the story in a visually-descriptive language. That's really neat! I can imagine this is the beginning of telepathy.
