Also hah! I saw someone once counter, "If category theory is so universally useful, tell me how it helps the study of differential equations?" The ISA "sprint"

Also hah! I saw someone once counter, "If category theory is so universally useful, tell me how it helps the study of differential equations?" The ISA "sprint" https://www.ias.edu/math/sp/hprinciple_flex_geometry_pdes https://www.ias.edu/math/sp/hprinciple_flex_geometry_pdes referenced by the article mentions PDEs and Fukaya categories, which I hadn't heard of, so hah! Just don't ask me to explain it :D
