"Laid off" may be more appropriate than "fired", but in essence, removing the need for costly labor is often the main "value" of any technology. Society as a whole comes out ahead from it, I mean for all the ice transporters and merchants put out of a job by electric refrigeration, and all the sailors put out of a job by modern cargo ships I think we're better off for it. But at the individual level it does make one uneasy about the prospects of individuals affected by it. My personal conclusion is that people have a personal duty to anticipate and adapt to change, society might give them some help along the way but it doesn't owe them that their way of life will be maintained forever.
