Interesting take on The Time Machine by H.G.Wells.

Part one assumes that your question is referencing industrialized populations, or those about to embrace the technologies of which you write. (not sustainable).

Part two then decreases in probability, unless the economic systems that require a proletariat maintain their land and water sovereignty. (so who’s next, for the insatiable resource appetites of the war machine?)

Alternatively, the proletariat become so useless we are even more rapidly killed off by big pharma, GMOs in our food and water, and enslavement. The NWO is just analyzing the data for the most efficient methods, as we speak.
