"Anthropocene, Capitalocene, Chthulucene: Staying with the Trouble Sympoiesis, not autopoiesis, threads the string figure game played by Terran critters. Always many-stranded, SF is spun from science fact, speculative fabulation, science fiction, and, in French, soin de ficelles (care of/for the threads). The sciences of the mid-20th-century “new evolutionary synthesis” shaped approaches to human-induced mass extinctions and reworldings later named the Anthropocene. Rooted in units and relations, especially competitive relations, these sciences have a hard time with three key biological domains: embryology and development, symbiosis and collaborative entanglements, and the vast worlds of microbes. Approaches tuned to “multi-species becoming with” better sustain us in staying with the trouble on Terra. An emerging “new new synthesis” in trans-disciplinary biologies and arts proposes string figures tying together human and nonhuman ecologies, evolution, development, history, technology, and more. Corals, microbes, robotic and fleshly geese, artists, and scientists are the dramatis personae in this talk’s SF game."
