For example, cashiers. There are still many people spending their lives dragging items over a scanner, reading a number from a screen, holding out their hand for the customer to put money in, and then sorting the coins into boxes.
How hard can it be to automate that?
The one I'm desperately waiting for is serverless restaurants—food halls already do it but I want it everywhere. Just let me sit down, put an order into the kitchen, pick it up myself. I promise I can walk 20 feet and fill my own drink cup.
Call it what you like but replacing the work of humans one for one is difficult and usually not necessary. Reformulating the problem to one that machines can solve is basically the whole game. You don't need a robot front desk worker to greet you, you just need a tablet to do your check in.
Like checking in at the airport via kiosk/app for example. Do you consider that to be "doing the work" of the desk clerk? Or say ordering at a restaurant by scanning a QR code, in both cases I have to look at the menu, decide what I want, and input my order into a system. But with the QR code there's no longer a human necessary.
