When people ask whether virtual reality will be a real thing or just the next 3D, what I always say is, 'Take a headset, walk outside, and the next person you meet, put it on them and see what the reaction is.'

By irreducibly complex I mean a single system composed of several well-matched, interacting parts that contribute to the basic function, wherein the removal of any one of the parts causes the system to effectively cease functioning.
