Is "loving math for maths sake" just about knowing the answers? I think one can love math for exactly the process and understanding that a several-thousand-line uncommented Lean proof denies. If a deity rearranged the stars to spell out "The Riemann hypothesis is false" for a night, would that be intellectually sufficient?

the way LLMs write math is not beautiful. it is exactly analogous to the software that LLMs develop is not beautiful. it may achieve impressive end products, but if you like understanding the methods/architecture, looking under the hood is often a field of horrors.

You feel lean4 proof, that you 99.999% chance not understand is beautiful?
