Specialized drones maintained the farm sections, which were producing all the kudzu you could eat. Yum. Of course, I didn’t have to eat it, what with being a computer and all, but the humans were not so lucky. Until the colonies were to the point of being self-sustaining, everyone’s daily calorie intake was up to fifty percent kudzu. And because of kudzu’s digestive side-effects, meals and other social gatherings tended to be outside. Or involve open windows.
