Why is making a job obsolete destroying a job? I see it as progress. It frees up a human resource to find a more rewarding opportunity. Any worker(s) made redundant certainly don't feel that way at the time of impact because they get the opportunity to evolve by trial. One observation I've made regarding replacing people with technology is the inherent brain drain: all the details get abstracted away into the new technology or system and no one remembers or thinks about them anymore. When something goes wrong, those details matter. That creates a different demand and the cycle continues.
