Uh, are you sure about that?
Wouldn't he replace it with another?
This substitution phenomenon has certainly worked for a long time, from agriculture to industry, then from the latter to the tertiary sector, but with AI this latter sector is concerned. New jobs will result, but not in the measure of destruction (there is a thread dedicated to this important question).
What is dramatic is that hardly anyone questions a work-based system without questioning its content; I mean that everyone talks hysterically about "creating jobs", but without worrying whether these hypothetical creations would be useful or not, since this necessity only applies to the intrinsic functioning of the system (as well as the essential function of the commodity is only to increase the initial capital of which it is the bearer, therefore regardless of its particular nature and its utility [insofar as this last criterion is not opposed to market exchange]).
