The whole debate about whether or not he can realistically do this based on the state of the technology seems like a side issue to me. What really stands out is that he and CEOs like him would imply that a large, critical segment of their work force is not especially valuable to them, and also that they don't really see them as people. Rather, they are things that can be set aside as soon as they aren't needed.
These business owners aren't going to see us as people until we force them to. Unionize and strike.
