Having proper sub-vocalization interfaces would be so cool! A 19-channel EEG does seem a bit invasive though (from a social aspect, I understand that it's used here in a medical context).

I'm not interested in seeing this technology progress any further. The ability to read someone's inner, unspoken thoughts is too easy to weaponize against them.

I wonder whether a subject could poison the process by consciously thinking about something unrelated in the same way that public speakers used to get past stage-fright. As you look out across the audience picture something funny, like your boss in a pink tutu.
