Those jobs won't get automated soon? I guess you haven't been paying attention especially when you list cashiers. My local grocery store is using self-checkout completely with a couple of managers to keep watch. Even grocery stores might not be here soon because they will just deliver you the food with their self-driving car.
I don't know what you do for a living, but you better find a job in IT so you can stay on top of things.
Oh, we have self-checkout counters, too. Thing is that not everybody uses them and prefers going to the cashier, and the self-checkout counters still have some cashiers to help the people out when they have problems. In other words, while there will probably be a bit less cashiers, they just won't go away.
