"“On the other hand it is possible that human control over the
machines may be retained. In that case the average man may have
control over certain private machines of his own, such as his car of
his personal computer, but control over large systems of machines will
be in the hands of a tiny elite -- just as it is today, but with two
difference. Due to improved techniques the elite will have greater
control over the masses; and because human work will no longer be
necessary the masses will be superfluous, a useless burden on the
system. If the elite is ruthless the may simply decide to exterminate
the mass of humanity. If they are humane they may use propaganda or
other psychological or biological techniques to reduce the birth rate
until the mass of humanity becomes extinct, leaving the world to the
elite. Or, if the elite consist of soft-hearted liberals, they may
decide to play the role of good shepherds to the rest of the human
race."

Would the elites actually try to kill off most of humanity once the majority of jobs are replaced by machines?
