The theoretical problem the 'researchers' posed is nonsense. At the distance one has to be for a decent transfer speed, one may as well being sitting at the keyboard. They also miss the point of air-gapping: the computer is isolated from the most dangerous external threats. For an air-gapped computer to be compromised one would need physical access which limits the number of people dramatically to maybe a handful. Exploits with an effective range of a few meters that can easily be blocked (play music in the room) are not worth worrying about.
