I did read the summary and see what you saw, but that still leads me to believe the headline of the article is clickbait and that the authors don't understand that action signalling doesn't require the same bandwidth as information processing, but even then it's way more than 10b/s.
Look at a backhoe. It has a few levers and a couple pedals. EXTREMELY simple interface. Each lever and pedal is basically 1 bit for engage/disengage, but the operator has to process orders of magnitude more sensory info to operate it properly. You could use an arduino to control a backhoe, but you'd need quite a powerful computer to know what to tell the arduino to do. This shouldn't surprise anyone. Knowing how to use the tool well is always far more complicated than simply knowing how the tool operates.
