2025-02-24 22:47:03 +0100 <lyxia> it means that types of the form "forall A : Set..." are not sets. Sets cannot contain elements that quantify over the universe of sets.

2025-02-24 22:22:51 +0100 <ncf> i know you can make sense of impredicative encodings via abstract nonsense like "if Set is impredicative then the category of sets is large-complete so the limit of the identity functor gives an initial algebra for every functor" but like... that's what i mean by weird
2025-02-24 22:21:55 +0100 <ncf> category theory makes normal inductive types make even more sense

2025-02-24 22:20:22 +0100 <haskellbridge> <Bowuigi> Hinze's Generic Programming with Adjunctions illustrates this perspective quite well, with more advanced examples found in the HoTT blog
2025-02-24 22:19:32 +0100 <haskellbridge> <Bowuigi> They are, but Category Theory makes them make sense I guess
