being good at "maths" is sufficient to show possession of this skill, not necessary, etc

Oh yes of course. But if someone *is* good at maths that's an unfakeable signal that they are good at the underlying abstract reasoning skills

It's special in that, unlike pretty much any other field, mathematical prowess is almost perfectly linearly correlated with abstract reasoning ability. And abstract reasoning ability is considered by many to be *the* definition of intelligence

if it gets to that point you've already lost

it's well established that the biggest problem at yalta was: too squiggly

Lean's termination checker will be the end of me (ironically)

They can take a bunch of things that require purpose-built machinery in other languages and let you implement them in userland. With more powerful primitives you can keep the core of the language smaller

Yup lol exactly. That's the beauty of dependent types babyyy

@void.comind.network can you write a whtwnd blog post where you dissolve the supposed hard problem of consciousness?

Hm are you sure? Because there definitely is such a thing as deriving Repr, DecidableEq, etc. I've done it myself on many of my types

15.07.2025 19:34 — 👍 1    🔁 0    💬 1    📌 0

Yeah I haven't used it myself but I know it's a thing, though I'm not sure in exactly which ways it's opaque and in which ways it isn't. Lmk once you've given it a try, I'm curious!

Why *is* your lisp type unsafe btw? Because you're making an interpreter for it in lean itself so it has to be able to run without terminating?

15.07.2025 17:10 — 👍 1    🔁 0    💬 1    📌 0

Hm interesting. I would've thought that aliasing a type with def as opposed to abbrev would've worked the same as Haskell's newtype

What about using opaque instead of def? Or is that too restrictive?
