Soon, that was the essence of the Luddites argument, and history has proved them spectacularly wrong.
A person only has one pair of hands, and only 24 hours in a day, so increasing wealth rests on the ability to produce more with the same number of hands in the same amount of time. Economic growth comes from improvements in productivity achieved by automation.
Think about mediaeval times, perhaps 70% of the workforce were employed working the land just to provide enough for everyone to eat. Nowadays the same amount of food can be produced by say 5% of the workers using machinery, so if the Luddites were correct that would mean that the other 65% or so are now unemployed. But they aren't of course, they're all making other things that we simply wouldn't have if everyone was still tied up working the land, things like cars, washing machines, TVs etc. etc.
It looks like automation causes unemployment because it does in a very short term sense, but in the long run people are re-employed doing other things that wouldn't have been possible if automation hadn't freed up some labour.
