Science is entering a structural saturation era. As artificial intelligence increasingly automates the production of scientific outputs, the traditional value of publications as the primary unit of science is being fundamentally challenged. This paper proposes that the next evolution of science may not concern new discoveries, but a transformation in how knowledge itself is understood. From knowledge as accumulated structure to knowledge as sustained generativity. This work introduces the concept of Generative Science as a possible foundation for post-AI scientific civilization. Highlights • Proposes a new scientific paradigm: Generative Science, shifting the focus from publications to generative research trajectories. • Introduces a UPCT-based reinterpretation of scientific activity as a generative cycle (Φ → G → S → Φ′). • Explains why AI development may reduce the epistemic value of structural knowledge production while increasing the importance of generativity. • Identifies open repositories such as Zenodo as early infrastructure for process-based science. • Suggests that the next scientific revolution may be ontological: redefining knowledge from structure to generative participation. Overview Modern science has been built upon the stabilization of knowledge into structured outputs such as journal publications. This structural paradigm enabled cumulative progress, reproducibility, and institutional validation. However, it also created a hidden constraint: the generative processes that produce scientific insight have become largely invisible within evaluation systems focused on finalized outputs. This paper argues that science may now be approaching a structural saturation point. As artificial intelligence increasingly automates structural research functions—paper writing, literature review, and evaluation—the scarcity that once justified structural metrics is disappearing. As a result, the true differentiator of scientific contribution may shift toward generative capacity. Using the Universal Phase Crystallization Theory (UPCT), scientific activity is reinterpreted as a generative cycle: Φ → G → S → Φ′ where Φ represents generative potential, G relational interaction, and S structural stabilization. Within this framework, modern publication systems may be understood as structural optimization systems that risk suppressing generative exploration when overemphasized. This work proposes the concept of Generative Science as a complementary paradigm to structural science. In this model, scientific value increasingly lies in sustaining knowledge evolution rather than merely producing stabilized outputs. Open research infrastructures such as Zenodo and arXiv are interpreted as early manifestations of this transition, enabling research to be recorded as evolving trajectories rather than isolated products. The paper concludes that the next transformation of science may not be technological but ontological: a shift from viewing knowledge as accumulated structure toward understanding knowledge as sustained generative participation. Such a transition may redefine the identity of the researcher, the meaning of expertise, and the future architecture of scientific institutions.
