What entirely new, previously impossible job does automating away McDonald's workers create, that formerly employed McDonald's workers are qualified for? Are we going to send them all to coding bootcamps so they can program the kiosks and... oh wait, those jobs are already taken, never mind.
Your statement tends to be true when automation involves some kind of revolutionary technological paradigm shift, and the number of people being automated out of work is sufficiently small that societies can easily reabsorb them into the workforce. But most modern automation doesn't create new jobs or new technologies, the infrastructure for automation already exists and is stable. It just removes jobs, and at an unprecedented scale.
