Embodied Biographical Alignment (EBA): Beyond Control — Shared Developmental Lineage and the Human–Machine Horizon

Embodied Biographical Alignment (EBA) began from the hypothesis that information about a human life may not be equivalent to the causal consequences of living through a temporally extended developmental history. Published EBA v0.2.1–v0.2.3 progressively narrowed this intuition into testable questions concerning transformative integration, developmental equivalence, and plural developmental history. This philosophical–scientific research note returns to the wider horizon of the programme. It argues that alignment should not be reduced to control and asks whether humans and machine intelligence could develop enough shared history to remain intelligible to one another as both continue to change. The paper develops the concepts of relational biography, co-developmental coupling, post-relational development, developmental inheritance, and shared developmental lineage. It further proposes that future machine intelligence might become not merely a product of human design, but a developmental descendant of a long human–machine history. The paper does not claim machine consciousness, subjective experience, or automatic moral improvement. Its purpose is to preserve a broader research question while keeping the technical hypotheses of EBA open to falsification.
