To compare this to automation in the pass is a false equivalency, as humans have always been needed to be a part of the chain in some capacity. In short order, a McDonald's will not only have an entire store run by automation, the maintenance will be done by automation, and the factory where the parts are created will also be in that restaurant in the form of a 3D printer and same day delivery systems via drone.
Once this is established in a proven model, humans cannot improve upon this, and the need for humans for almost any task decreases immediately. Niche boutiques will pop up with human made burgers, but they will be like fine dining, and seen as a treat if done well, cashing in on mostly the nostalgia of those that we're not born natively to this environment.
