Could you build this?
No Formally proving every single theorem and exercise from Michael Spivak's rigorous Calculus textbook in Lean 4 requires deep graduate-level mathematical expertise and specialized interactive theorem proving skills that LLMs cannot reliably synthesize on their own.
What it would actually take: This project requires an expert in Lean 4 and real analysis. The tech stack relies on Lean 4, Mathlib4, and interactive theorem provers. The core challenge is manual formalization, tactic construction, and mapping subtle mathematical intuition into machine-verifiable proofs across hundreds of intricate textbook problems.
