The point is that when automation "pushed out jobs for the masses", despite the doom mongers saying it would leave us with hundreds of thousands unemployed, those jobs were effectively transferred elsewhere. Large-scale manufacturing has been on automated production lines for twenty years or more, and it hasn't caused an implosion of the world economy (we left that to the bankers).
However this is about a technology which replaces a service rather than a product. A service which can not be replicated by an automated voice recording.
It can be replicated by a machine and has been effectively. It is a simple, repetitive process that is perfect for self-service. In my shopping experience, a checkout clerk doesn't perform any commercial action that the self-service till can't; I pack my own bags at either till, I can scan items as quick or quicker than a clerk, type in a barcode if the scanner doesn't recognise it, weigh fresh produce, and use loyalty points and vouchers. As mentioned, there are assistants to help with problems and authorise purchases if necessary.
As supermarkets and high street stores introduce more and more self serve machines, eventually the general public will get used to using them.
Like the public have got used to using Internet sites for buying financial services? Insurance, loans, credit cards, bank accounts can all be done online; holidays can be booked and paid for without visiting a travel agent, plus checking in for flights; you can pay for your car tax or buy postage, pay your utility bills (or change supplier) - all the at the click of button, and all end to end processes that have removed humans.
This is the nature of a capitalist society, increase profits - this is happening by increasing efficiency through greater use of technology and is nothing new.
If you don't want to support it, shop at your local corner shop or farm shop, buy your insurance from your local broker, go to the travel agent, buy a hand-built car etc. and pay for the privilege, while the tech adopters compete with each other to lower their prices; I would applaud you for doing so - however, don't think it's going to destroy the jobs market (any more than has been) because it will create new demands and opportunities.
