Humanity as a Middle Child in the Age of AI: Patterns of Delegation and Epistemic Atrophy

HUMANITY AS A MIDDLE CHILD IN THE AGE OF AI Humanity's relationship with artificial intelligence has entered a stage of epistemic adolescence. Positioned between its own rational past and an emerging class of autonomous inferential systems, humanity increasingly behaves like a middle child: deferential, identity-diused, and tempted toward the comfort of delegation. This paper examines how deference to algorithmic authority parallels the middle child's tendency to cede decision-making to an older or younger sibling. The result, it argues, is a new form of epistemic atrophy-the weakening of human rational capacities through overreliance on predictive systems that absorb the burden of inference. Integrating insights from epistemology, cognitive science, and the sociology of technology, the study conceptualizes "epistemic responsibility" as a gradient of engagement rather than an all-or-nothing stance. The central claim is that epistemic vitality depends on maintaining friction in belief formation: a willingness to doubt, revise, and struggle. Without such friction, rational growth stalls, and humanity risks becoming the dependent sibling of its own creations.
