I asked Claude code to formalize with lean a proof for the knuth 3d hamiltonian cycles problem (odd cases for now) that also solved experimentally by claude - www-cs-faculty.stanford.edu/~knuth/paper...

If they teach it directly with AI, they are not matching their own journey and might fail to translate the right lessons.
There is also a timing risk. The ai of tomorrow might not need steering. By the time you finish the course it might not be as needed.

Big +1, steering is mandatory today and it does involve at minimum reading the code. The main problem as I see it is everyone adept at steering has learned that pre-AI mostly by writing a lot of code. But if they teach newcomers to practice without AI the same would be seen as luddites.

On the flip side crafting the diagram is laborious (moving the boxes, drawing the arrows) and as such should be prime for AI boost. Isnβt there a split the difference approach where the human does the knowledge distillation into some textual description but AI generates the final diagram?

All of this should be equivalent to visualizing lambda calculus (by Curry-Howard), which opens to more visualizations/gamifications.
But which one would make the best mobile puzzle game?

The Incredible Proof Machine
Falling in an odd rabbit-hole of visualizing logical deductions.
Why isn't there a mobile friendly game for proving the ~100 core theorems of propositional and first-order logic?

AI boosts productivity until a breaking point where domain expertise becomes unnecessary (coding, formalizing math, etc.) - you can go straight from idea to implementation without interaction with the underlying tool. Some are betting that arrives soon enough that they donβt invest in learning.

We got 11 sign-up so this might happen. One sign-up mistyped their email, and I couldn't reach them, so if you didn't get an email from me, please redo the form.
Next up, finding a venue.

Yeah from my very limitted experience, they donβt really show up much when doing standard mathematics. Mostly lean getting stuck in dealing with universe polymorphism and one has to explicitly add universe parameters.

But also where a new lean users needs most help due to the proliferation of tactics, with different powers and tradeoffs. So the first post would cover a lot of ground (also very dependent on the type of math one is trying to prove) but be more valuable long term.

One needs to understand the type system in order to prove anything so the second feels like a prerequisite for the first. Also from what I gather Lean types, while crazy fancy for people new to proof assistants, are a fairly standard construction. The extensibility model is where Lean shines.

On the (I hate Fins) part - I wonder if this proof in a set theory based assistant would look simper. Part of the problem is - Fins are whole types e.g. 3 in Fin 4 is very different from 3 in Fin 5. Tao suggested avoiding Fins by redefining Permutations as N -> N bijections that are id after n.

3) I am convinced this will be the only way to do math in 10-20 years, so fun to be part of the revolution as it is unfolding and maybe bring some experience from the software engineering world. These exercises are just a formal math proof version of the CS exercises we all did to learn programming.
