Actually insane nobody talks about the first relevant piece of information right at second 4 and the title drop of the OP. The humans plant fucking microchips in newborn babies which are probably the same quadratic thing on the hands of Tomoro and the other cleaner to power up their Sapotama. I asume that are biochips as well so the Sapotama get the information needed to track fitness and nutrition.

Now what would be actually insane is if an uncontrollable AI get access to the programming part. If Digimon are bugged AIs then what if the big AIs used for AI management get out of control? That Digimon could practically kill off the humans via the Sapotamas.
