No, the point is what if: 1) The easy to do and train for jobs are all automated away. 2) The available jobs require PhD level expertise to do.
If I've studied for 8 years to get my quantum physics PhD to get my job as a technician at Quantum World, then it's going to be damn hard to retrain for 8 more years to get a PhD in Natural Language Processing to work phone support at AutonomaTech.
People are becoming increasingly specialized. If automation eliminates the easy to learn jobs, it gets harder to jump from one specialization to another.
