I am reading all your replies, guys… not replying because I am still mulling the question over. Seems to me there is something, some meaning, hidden in what we in the industry call the “man-machine interface”. It has changed a lot from Charlie Chaplin’s Modern Times assembly line behemoth to a stage where we are hard-put to define where man ends and where machine begins. I have to think on it, or let it go. Maybe the insight will come by itself.
