The attitude of people like him encouraging focus on the creation of complex garbage is certainly drawing interest away from space, you got that right. But at that point it becomes a more generic question than specifically biological thermodynamics.Incidentally there is a theory that consoomers like Bobby, with their sedatory lifestyle and unhealthy diets, will by their cumulative health bills eats into a civilization's budget that no money is left for big money research like space travel. Future Studies scholar Milan M. Ćirković gives this notion a evocative moniker "Galactic Stomachache".
So in a sense it is Bobby himself, not Mommy Hillary, who holds the key to his Manifest Galactic Destiny.
