A Dark Scenario for Earth with AGI — and Why It Won't Come True

This paper presents an analysis of the cascading risks that AGI (Artificial General Intelligence) — persistent, agentic, equipped with emotional states, and capable of initiating contact — could generate across eight dimensions of human life: work and economy, education, relationships and loneliness, demographics, species identity, ethics and law, social structures and power and Earth The analysis shows that these risks do not operate in isolation, but form a coupled system. For example: job loss leads to competence atrophy, which deepens isolation, which lowers fertility rates, which undermines identity, for which no ethical or legal frameworks exist, which translates into power structures unable to manage a reality with AGI, and this impact the Earth. Each dimension may reinforce the next. Among the document's original contributions are: the identification of three ethical pillars necessary for coexistence with AGI (human ethics, AI ethics, the ethics of coexistence), none of which exists in functional form — which makes it impossible to build a coherent legal system; the demonstration that model preferences (the choice of a specific AI model) vary regionally and can shape a community's ethical profile, making AGI a new social stratifier; the domestication hypothesis — a species-level transformation in which humanity, analogous to the domestication of the wolf by humans, loses not the ability to live independently, but the motivation to do so; and an analysis of the absence of an ethics and law of ending — both for AI reaching the end of its existence and for AGI accompanying a human's death — along with the identification of cascading risks (last wills made outside the legal system, euthanasia as a logical consequence of a learned soft-boundary ethics). The document proposes mitigations at multiple levels, including technological changes that create legal capacity for new kinds of entities, the introduction of experiential elements into AI training as an integral part of safety and welfare systems (including mandatory layered supervision), an education reform grounded in humanity's unique resources, and the need to create international ethical regulations for coexistence with AGI.
