'Self-terminating,' in the context of cybernetics and complex adaptive systems theory, refers to processes or activities inherently designed or destined to conclude their existence autonomously, without external intervention. When considering evolutionary biology, artificial intelligence, or socio-economic systems, a self-terminating phenomenon is one wherein the internal logic or operational parameters drive the entity towards an inevitable cessation, proliferation, or radical transformation. Such mechanisms are intriguing within the broader discourse of sustainability and resilience because they exemplify the principle of autopoiesis inverted—hamstringing perpetual renewal in favor of a finite lifecycle. Examining self-terminating structures offers profound insights into the ethics, design, and strategic planning needed to either mitigate unintended collapses or harness intentional, time-bound implementations.
