There's a critical distinction between a proof (which establishes truth) and an explanation (which provides understanding). Even when a complex mathematical problem is solved, there remains an 'unsolved expository problem' of making the solution comprehensible. This need for clarity and intuition will remain a crucial area for human or AI effort, even after theorems are proven.

Top AI models are now solving major open problems in mathematics, leading some in the field to feel their core purpose is being automated away. This isn't just about tools; it's a profound identity crisis for a discipline built on human ingenuity and the pursuit of solving theorems.

An AI model disproved a mathematical conjecture not through a flash of creative genius, but by methodically applying a known technique from a different math subfield. This highlights AI's current strength: synthesizing vast, disparate human knowledge rather than generating truly novel, alien ideas. It's an exhaustive librarian, not an intuitive genius.

A common fear is that AIs will produce billion-line proofs of theorems without offering human insight. However, an alternative and perhaps more likely future is that their superhuman capabilities will be applied to explanation. They could take complex, human-incomprehensible proofs and find novel ways to make them intuitive and easy to understand.

Expert mathematicians adopt formal tools like Lean not primarily to catch errors, but to offload tedious, low-level deductions. This automation allows them to operate at a higher level of abstraction and focus their cognitive energy on creative intuition and problem-solving strategy.

As AIs automate theorem proving and even explanation, the role of human mathematicians will shift. Instead of being creators, they will act as curators, using their taste and social connection to guide others through the vast, AI-generated landscape of mathematical ideas. Their value will lie in providing motivation and a human-centric narrative.

Future AI-driven mathematical discoveries will likely follow two paths. One is finding 'lightning bolt' connections between existing, disparate fields (e.g., number theory and physics). The other, more profound path, is 'mountain building'—constructing entirely new theoretical frameworks, a skill signifying a much higher level of general intelligence.

Proving theorems is only part of math. Axiom is developing tools for the pre-conjecture phase, helping mathematicians find interesting examples and constructions (like graphs or sequences). This AI-assisted discovery builds the intuition necessary before a formal proof can even be attempted.

Moving beyond solving existing problems like the Millennium Prize problems, the true test of advanced AI in mathematics will be its ability to generate novel, interesting conjectures and create new, unifying definitions. This represents a higher tier of mathematical creativity, akin to the work of the greatest mathematicians who frame the questions for others to solve.
