Scientists have found a way to decode a stream of words in the brain using MRI scans and artificial intelligence.https://www.npr.org/sections/health-shots/2023/05/01/1173045261/a-decoder-that-uses-brain-scans-to-know-what-you-mean-mostly
While not perfect, this is some seriously scary stuff.
FWIW the researchers themselves did recognize this…
Although it’s nowhere near being able to decode spontaneous thoughts in the real world, the advance raises concerns that, with improvement, the technology might mimic some type of mind reading. “Our thought when we actually had this working was, ‘Oh my God, this is kind of terrifying,’” Huth recalls.https://www.science.org/content/article/scientists-use-ai-decipher-words-and-sentences-brain-scans
Participants have to consent to being “read,” and there are ways to prevent the software from figuring out even the “gist” of what they were thinking.
Still, imagine if some nefarious criminal group (or governmental agency, if there is a difference) decided to force someone to consent to have their thoughts read.
It’s getting harder and harder to distinguish scifi from reality.
