What will come first, a time when one corporation owns everything or mankind's physical demise?
Answers:
Both will come at duplicate time, as they will mutually effect respectively other.
And within the process, humans will be divided into two species, an underground-dwelling Worker Species, and an above-ground living, clueless Master Species.
One will eventually *devour* the other, count on it.
mankind's physical demise
Probably mankid's physical demise, cause directly, or indirectly by this corporation.
