“They’re calling the technique “mind captioning,” and it may represent an effective way for transcribing what someone’s thinking, with impressively comprehensive and accurate results.”

It is certainly not reading of specific thoughts, but nonetheless statistically the results are way above just random guesses, with some sounding impressive. And yes, it seems AI does the number crunching to arrive at suggestions.

As with any technology, there can be good and bad applications for it. The usual culprits will try to exploit the bad side, but think of the good for those with seriously impaired communication capabilities (stroke, aphasia, and other medical difficulties).

Right now, of course this is not possible yet to use without an MRI machine, but it is quite promising so far, and possibly better ways to scan will be found.
