if somebody has worked most/all of their life in a low-education unskilled labor job (the kind that are most likely to be disrupted by computers), who says they even have the ability to become a robotologist or something very intensively knowledge based? In the future these will really be the only kinds of jobs computers cant do. The problems here are much more complex than the Luddite issues of yesteryear, and its disingenuous to write somebody off as a dumb Luddite.
