The developmental process through which children learn, by observing the adults around them, what boundaries are possible, how they are maintained, and what their maintenance costs — with generational consequences for the cognitive infrastructure of future adults.
Boundaries are not innate. They are learned — absorbed through immersion in households where adults model the practices of domain construction. The child who watches her parent close the laptop at 6 p.m. and place it in a specific location is learning, without being told, that domains exist and that their separation requires effort. The child who watches her parent answer Slack messages at dinner is learning, equally implicitly, that presence is partial, that attention is negotiable, that the interesting thing is always behind the screen. Nippert-Eng's framework applied developmentally reveals what the AI discourse has not addressed: a generation is being raised in households where boundary infrastructure has collapsed, and these children will enter adulthood without the cognitive scaffolding for boundary construction — not through parental failure but through structural absence of modeling.

Children are empiricists of the highest order. They do not listen to what adults say about boundaries.
