This paper introduces the concept of HUMROBOT as a philosophical framework for analyzing the transformation of human cognition in technologically mediated societies. As artificial intelligence systems, algorithmic decision-making tools, and emerging neurotechnologies increasingly participate in human cognitive processes, the boundary between assistance and delegation becomes increasingly fragile. The paper argues that this shift threatens what is defined here as cognitive sovereignty: the capacity of individuals to retain control over their mental processes, including thought, memory, judgment, and decision-making. HUMROBOT: Cognitive Sovereignty in the Age of Algorithmic Decision-Making Rather than rejecting technological progress, HUMROBOT functions as a critical figure that highlights the ethical and social implications of cognitive hybridization. The analysis examines delegated thinking, the erosion of autonomy, and the diffusion of responsibility in algorithmically guided environments. It also explores how technological optimization may reshape freedom, identity, and moral agency without explicit coercion. By situating HUMROBOT within contemporary debates in the philosophy of technology and ethics, this paper calls for a conscious and ethically grounded approach to humanmachine integration. It emphasizes the necessity of protecting cognitive sovereignty as a condition for preserving human autonomy and dignity in the digital age.
