I can suggest an equation that has the potential to impact the future: 𝐍𝐚𝐭(𝐇𝐨𝐦(−, 𝐶), 𝐹) ≅ 𝐹(𝐶) + AI Given a category 𝒞, a functor 𝐹 : 𝒞ᵒᵖ → 𝐒𝐞𝐭, and an object 𝐶 ∈ 𝒞. This equation combines Yoneda’s famous Yoneda lemma, which relates a category (𝒞) to…


I think this is more like a particular choice of semantics for programs, which makes sense in some contexts but not others. Or maybe I'm missing the point that all programs can be reduced to these somehow?

Whoa I just learned that interfaith marriage is illegal in Israel!! What the fuck?? This is insane.

Still getting weirded out about how: Lax functors C -> Span And Lax normal functors C -> Prof are the same thing

For R&D community nucleation, it’s exciting that @ToposInstitute opened a UK office, relocating @u_map_prop and @myers_jaz; while @JadeMasterMath and @tangled_zans used our funding to launch a new nonprofit research institute in Glasgow (GLAIVE: Glasgow Lab for AI VErification).

You, foolishly: a double category has horizontal and vertical morphisms Me, wise, laying flat: no those are vertical and horizontal morphisms

Yes exactly. The trick is to find the right generality where the definitions have canonical choices

A function a -> a only has one sensible implementation, a function Int -> Int has many—polymorphism is recessive. The implementation is constrained/clarified by the generality of the interface. Programmers warn of "premature abstraction," but this is confused w.r.t. foundations

Linear algebra is mother


I don't think this is fair. Think about how hard it is for a machine to distinguish "hallucination". There are just endless unknown unknowns.

The fact that LLMs still hallucinate 2 years after the initial release means: 1. Nobody knows how they actually work to fix them 2. Nobody actually cares
