We’re racing towards a future in which devices will be able to read our thoughts.

You see signs of it everywhere, from brain-computer interfaces to algorithms that detect emotions from facial scans. And though the tech remains imperfect, it’s getting closer all the time: now a team of scientists say they’ve developed a model that can generate descriptions of what people’s brains are seeing by simply analyzing a scan of their brain activity.

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.

“This is hard to do,” Alex Huth, coauthor of a new study in the journal Science Advances, and a computational neuroscientist at the University of California, Berkeley, t
