TL;DR
The paper advocates a cognition spaces framework to compare cognitive processes across natural, artificial, and hybrid substrates, moving beyond substrate-based definitions. It defines three morphospaces—basal cognition, neural cognition, and human-AI hybrid cognition—each with distinct axes and occupancy patterns that reveal evolutionary and design constraints. By analyzing voids and hybrid opportunities, the work highlights how development, embodiment, and interaction shape cognitive possibilities and identifies hybrid cognition as a promising frontier for richer, scalable cognition. The framework has implications for designing resilient human-AI systems, understanding collective cognition, and probing new forms of complexity, while cautioning about alignment, autonomy, and dependency risks.
Abstract
Cognitive processes are realized across an extraordinary range of natural, artificial, and hybrid systems, yet there is no unified framework for comparing their forms, limits, and unrealized possibilities. Here, we propose a cognition space approach that replaces narrow, substrate-dependent definitions with a comparative representation based on organizational and informational dimensions. Within this framework, cognition is treated as a graded capacity to sense, process, and act upon information, allowing systems as diverse as cells, brains, artificial agents, and human-AI collectives to be analyzed within a common conceptual landscape. We introduce and examine three cognition spaces -- basal aneural, neural, and human-AI hybrid -- and show that their occupation is highly uneven, with clusters of realized systems separated by large unoccupied regions. We argue that these voids are not accidental but reflect evolutionary contingencies, physical constraints, and design limitations. By focusing on the structure of cognition spaces rather than on categorical definitions, this approach clarifies the diversity of existing cognitive systems and highlights hybrid cognition as a promising frontier for exploring novel forms of complexity beyond those produced by biological evolution.
