Technology being developed by Facebook parent Meta, can scan brainwaves and guess what the person has heard. Neuroscientist Jean-Rémi King, a Meta AI researcher currently at the École Normale Supérieure in Paris, says this “could provide a viable path to help patients with communication deficits … without the use of invasive methods.”

It is not perfect yet. It lists the correct answer in its top 10 possibilities up to 73 percent of the time, researchers found in a preliminary study. The technique is magnetoencephalography, or MEG.

While I appreciate that this essentially saves the lives of people who are in vegetative states, it seems to me there are some dangers involved as well.

An AI can decode speech from brain activity with surprising accuracy – The research is still a ways away from helping people who can’t communicate through speech
