The human race has ‘advanced’ so far with technology, medicine and mass food production... that we are, in fact, helpless at self-sufficiency.
While millions can ‘log-on’ and ‘text-message’ in their sleep; how many of us can grow food, build shelter, find potable water. treat illness/injuries or raise livestock? We don’t have the skills to survive without mass production by others and government infrastructure. Robots are too late to matter.
