In today’s episode of the brain-in-a-jar show, scientists have built brain analog organoids consisting of about 10,000 neurons that can classify braille letters with about 61 percent accuracy, while teams of three organoids reached 83 percent accuracy.
Liu emphasized that this was an open-loop experiment, meaning that the organoids only received initial inputs without getting new feedback about their performance on the tasks. For this reason, the study does not prove that the organoids actually learned Braille, or were altered in any permanent way, just that they could classify Braille letters after receiving the electrical inputs.
So all they established is that the organoids respond in distinct ways to distinct signals out of the box?
Yup, this is basically an experiment in neural net classification, using actual neurons (instead of just math that simulates neurons)
Yes but that’s step one. If it’s repeatable, that’s useful.
Ah yes who needs ethics
I’m curious what you see are the ethical difficulties here… what line are you drawing, and where?
