Just because it happened twice--from ag to factories from factories to service--doesn't mean there will be a huge new need for employment. In the past, human consumption just increased. I'm not so sure there will be a need for all that much more consumption. If the promise of near human level AI occurs, we'd need to have exponential growth in consumption to keep up the pace.
Also, a lot of those jobs disappeared forever in the third world and never came back. Ag jobs were never really replaced with manufacturing job. Only now are some third world countries getting manufacturing jobs. If they are replaced with automated manufacturing those coding, engineering, and management jobs will go to the first world.
So maybe it works out for America and Europe. But someplace like Indonesia and India get permafucked yet again by a new industrial revolution.
