Well that goes back to the original point though. Which is, that no education jobs will theoretically dwindle. If we have machines capable of handling all, repeat all no education manual labor jobs; things like picking fruit, delivering boxes, etc. Where will those people go?

They will be forced to acquire more education or skill oriented trades.

The concern is if humanity will be able to adapt to something it has never seen. Where creativity and thinking oriented jobs become more and more required.
