Recent discussions about using the Lean programming language for real-world software development highlight both its potential for writing fully verified code and significant practical obstacles. Commenters argue that accurately defining software specifications remains difficult, and that strict proof-oriented safety measures can often be bypassed by developers seeking convenient workarounds. Additionally, while AI might eventually generate these proofs, human guidance remains essential to ensure the verified code actually aligns with complex user needs and avoids creating incomprehensible technical debt.
