The same arguments were raised the last time something like this happened.

And while it is true that a farmer can go to work in a factory there is very, very little overlap between these two professions (could a factory worker go tend a farm and survive? Unlikely) -- just as there is little overlap between cleaning toilets and being a cashier in a shop.

Oh and cashiers are not going to be replaced by the same AI that can clean a bathroom, do the dishes and wipe the floor.
