There was a similar study reported the other day about using FMRI imagining and AI to recreate the “thought content” of someone’s brain. It required training for the AI in the person’s brain and some other training. It does seem these techniques can work with some specified models, but yeah, it doesn’t seem like hooking someone’s brain up to this would create a movie of their mind or something.

I think the more dangerous part is “This is step 0,” which this tech would have seemed impossible 10 years ago. Very strange times.
