Technically, there is a fourth economic sector. The quaternary industry is what computer programming and research positions fall under. However, that doesn’t mean we can all realistically move to that sector, because it would require every person without a job to go through a masters or doctorate program, which is especially difficult to do when everyone who needs it just lost their jobs, and the quaternary industry is also being automated, so the point still stands that automation will likely lead to most jobs being wiped out.
