And textile workers were put out of work in the 19th century because new machines rendered their jobs obsolete. But would you really argue that we should roll back back 200 years of progress in the textile industry just to employ more people? What about the fact that textiles would be vastly more expensive and of limited quantity? Do you choose to have all of your clothes hand-woven or do you let technology take those jobs?

The only real difference here is that it's a technology you didn't grow up with that is putting people out of work, so it's seen as unusual to you. We make this choice of technology over manual labour in virtually every industry every single day. But it's normal because we grew up with it. And the kids that grow up with this technology today will see this as normal too. Eliminating cashier jobs in supermarkets isn't fundamentally any different to eliminating textile worker jobs in the 18th century.
