I'm not sure how a piece of tech whose entire purpose is to help cut costs associated with human workers is going to generate more jobs. It may create some more service jobs for those with the skills to repair and maintain said kiosks but its not like McDonald's is going to hire back everyone that the kiosks displace out of the goodness of their hearts.
The kiosk has a net positive on job creation. You now have MANY companies that are designing and creating kiosks, these companies have now CREATED jobs such as software engineers, hardware engineers, marketing, hr, etc. Then you have factories all over the world that are now manufacturing these kiosks, these factories have now CREATED new jobs.
Even at McDonalds, new jobs are being created such as, maintenance and service engineers, software team that creates the ui, updates the menu, design the graphics and whatnot, networking jobs, etc.
The amount of jobs created all over the world because of the kiosks is numerous. We don't have the intricate financial details of McDonalds but just because a company implements tech doesn't necessarily mean their cutting costs, sometimes it costs them more but hoping the tech will help them gain even more revenue and off set the cost. Mcdonalds might be hoping these kiosks help them sell even more burgers, due to its ease and speed. People can even place their order and it will be ready before they get there.
Whenever automation replaces a physical labour job, it means that society has gotten richer, we are now more advanced. Please always think of the big picture and let's not regress to being luddites.
