It’s an interesting one that’s for sure, and I accept much of what you’re saying, but there have to be limits.
My job, and my success within it, is principally founded upon the relationships I have with the people I provide a service to. I’m busier than (or at the very least I’m as busy as) any of my cohort, not necessarily because I’m better than them at technical aspects of the job, but because of my people skills and ability to interact with, and gain the trust of, people across a wide spectrum of social class and background. This gives me a huge advantage over most of them, and a significant one over all.
Never say never, but I’m struggling to see how a machine is ever going to challenge that. I don’t doubt in a few years a machine will have a far greater knowledge and understanding of the field I operate in, and be able to come up with the correct answer more efficiently and correctly than me, but to some extent my response to that is “so what?”
There will be some jobs that a machine will not be better at. Maybe a minority, but a significant one would be my best guess.
