Someone has to maintain the systems that make this work, thereby creating new jobs in a more skilled field as well.

Society evolves, and so does the job market. Laborers rioted when threshers were invented, but they came to accept it and moved on to other industries. And on, and on, and on...

from what I understand a lot of people are unhappy with self checkouts, I mean there's not much of a time difference but a lot of workers were unhappy with having 1 employee handle 8 sco's vs 1 cashier per check out, and a lot of customers were unhappy because they can be clunky to use.
