In a machine-ordered code infested society, humans will be the new parasites.
Only a few humans will be the biggest threat to that society:
Because the old, chronical sick and disabled people easily don't fit the standardization of the average human being, and machines can't cope with their kind of unexpected behaviour at the moment. These people are usually the last to see modifications or innovations in the system coming their way, everybody knows this (and the extra price). A cheap exoskeleton doesn't suit up paralyzed or braindamaged persons by itself, like it does with iron man. Or what good do google-glass to a blind man? They are like that black man with a time-machine, in any time he goes he stays a loser. Henceforth, if we can transfer their souls in to a machine then their sins will too be transferred. And the council of machines will also be corrupted by sin. And so in that society humans will become parasites, inevitably.
So the true social construct of the machine-ordered society is limited by its modi operandi or it gets the vitium originis within the system.
