Ok. so "sewing machine" is a robot to place sensors without hitting blood vessels. These sensors have some wires that are attached to an induction loop of some kind for recording. Seems feasible. Density is variable and probably dependent on brain region (speculative). I imagine the next step is deep learning to classify neural/sensor patterns into specific actions.
