this particular library may not be as reliable as one would like to. but the approach is fairly simplistic and likely without an access to powerful data center computation power. as far as (!) you know - you have already acknowledged existence of such machines. what I'm advocating for is existence of slightly more exotic sensing mechanisms - available to be used en masse straight from the telecom towers. RMG as a successful substitute for EMG (which in turn is a substitute for EEG) in context of deciphering whatever data captured into inner monologue.
