I watched the video before and from what I remember argues that this hasn't actually happened before and cites that very few jobs were invented since industrialization. It's not about inventing new jobs. It's about shifting the workforce to other jobs. Doesn't matter if they are new or we had people doing it before. Did we have mathematicians, professors, teachers, doctors, etc. before the industrialization? You bet! Total percentage of the population working those jobs?
