Recalling real-world #history, #Calabi left Italy around the same time as #Fermi, for the same reason. (Nowadays the problem is that people tend to forget and repeat the errors of the past.)

Of the next generation, Tullio #Regge was more of an eclectic dreamer and a mathematician than a physicist like Fermi, which aligns him more closely with the abstract nature of n-category theory.

Eugenio Calabi died on September 25,. He was one of the most influential geometers of the 20th century. His former student Xiuxiong Chen says that “A lot of mathematicians like to solve problems that finish off work on a particular subject” . “Calabi was someone who liked to start a subject.” https://www.quantamagazine.org/the-mathematician-who-shaped-string-theory-20231016/.
