Kalyoncu's Great Filter Hypothesis: Intelligence as an Evolutionary Instability

This work presents Kalyoncu's Great Filter Hypothesis, a speculative theoretical framework proposing that the Great Filter may not only be an external catastrophe faced by intelligent civilizations, but also an internal instability produced by advanced intelligence itself. Version 2.0 develops the hypothesis into the Continuity-Decoupling Model. The central claim is that advanced intelligence, especially when combined with high information access and artificial reward substitutes, can make evolved biological imperatives less automatic: reproduction, kin investment, social bonding, long-term motivation, and intergenerational continuity. This version responds to major objections raised after public discussion of the earlier version, including the roles of capitalism, demographic transition, expansionist subgroups, post-biological continuity, seed ships, Von Neumann probes, and the distinction between technical possibility and civilizational motivation. The paper argues that intelligence does not need to destroy civilizations directly. Instead, it may weaken the biological and cultural foundations that make durable expansion feel necessary before civilizations have built reliable replacements for those foundations. This is a speculative theoretical paper, not peer reviewed.
