Of eating ...
Money (or better computer chips).
Because the money these days is mainly “virtually assets” (no physical counterpart) - I think it doesn’t suit the human physiology that well … we may adapt, or die in trying. 😳.
One of these crazy ideas, because the majority of humanity is still trying to generate more and more of it, mostly for a minority, but still - they try.
Wherein is the sense in that?
