The ongoing discussions and developments regarding Fermat's Last Theorem highlight the challenges faced in modern mathematics, particularly related to the use of formal systems like Lean. Expert mathematicians express frustration over the lack of clear documentation in the field, which often leads to gaps in understanding. While theorem provers like Lean could provide essential support for mathematical validation, there remains a divide between mathematicians who prefer traditional proof methods and those advocating for formalism. The community seems to be moving towards a blend of computational assistance in mathematics, raising important questions about documentation, proof reliability, and the future of mathematical communication. The comments indicate a wider recognition of the importance of accessible proofs and the potential need for shift in educational norms in mathematics to embrace more formal methods, alongside the recognition of unique perspectives and historical context within number theory.
