I think it's not just to check - it's to interpret, simplify, apply taste, basically get these proofs into a form that humans can grok and build on. AI could do all of that but the grok-ing -- as we are tapping the font of cheap proofs it still behooves humans to keep track of what we find interesting, keep internalizing and learning concepts and make sure whatever we're building right now will be generationally useful. At least that's my take
