all just hints of quantization vs gravity dualities popping up everywhere. reminiscent of modular/elliptic dualities that popped up everywhere. i think there's an isomorphism between these two dualities that goes beyond the trivial category theory-esque representation (which would hold even if they have no relationship) i bet there's a relationship though. see ryu-takayanagi and entanglement entropy vs how modular forms encode special algebraic symmetries.

but even if just the categorical isomorphism holds (with no meaning beyond the math representation), it would be interesting. it really would show that even seeing QM and GR as separate things that need to be linked is wrong and that they are just different instances of one gauge theory popping up its head in different contexts (GR being a gauge theory in the yang mills sense)
