If, for example, a robot like IBM Watson can search a patient's records or analyse an x-ray more effectively than a human, this is better for the nation's health and should be brought in. Over time, these different systems will hopefully start to see a whole organisation run more efficiently, which may result in fewer staff. But this will be an organic shift, that happens over a period time, and it will be for the greater good. You wouldn't expect to find labourers milling corn by hand today, when a machine is far more efficient. The only difference today is, we're not going to take any Luddites out the back and shoot them.
