It appears to be a battery. It appears to be a sack of food or seed. One thing leads to the next, and after awhile these mute, bald neighbors will be interacting regularly and these human survivors will find they are living a very high tech existence with remarkable neighbors. They will accept this because desperation fosters acceptance of solutions. The high tech communities of humans, who in many cases will be enclaves of the rich, who have used their wealth and power to carve out an area whose perimeter they can protect with the military which will become mercenaries to the rich in such situations, will find they do not get this type of assistance.
Arguments break out.
The mercenaries are hardly going to take orders from the idle rich when they have no power or authority and can't supply them with money or goods or anything of value. These pampered rich people will be slaughtered, and sometimes in unpleasant ways, by their angry mercenaries, who in many cases have thug tendencies and enjoy cruel games. So now we have gangs, chewing down everything they can get their hands on and then going on the loose after there is nothing more to eat. These types of people are not prone to plan and work with each other, so growing crops and gardens and the like is the least of their thoughts, but looting is. But when they go on the loose, they will in fact be turned away from enclaves of good hearted people, in the many ways we are able to deflect knowledge and attention.
