Grant Sanderson – AI and the future of math
"Describing why it was a valuable insight does not come from immediate utility... between the time of Lagrange like having this inkling of maybe symmetries of roots is the right way to go to where it all looks like modern group theory, like you've got this long span... it wasn't even passing the verified reward of human reviewers, right?"
Sanderson explained how Galois's revolutionary group theory insights from the 1830s took nearly a century to be recognized as valuable, with his papers initially rejected and misunderstood even by expert reviewers. This creates a fundamental challenge for training AI mathematicians, as the verification loop for truly novel mathematical concepts can span generations, making current RL reward systems inadequate for breakthrough discovery.

About this episode

In this episode, host Dwarkesh Patel interviews Grant Sanderson, creator of 3Blue1Brown, about AI's rapid progress in mathematics and what it reveals about the future of artificial intelligence. Sanderson, who is documenting AI's mathematical achievements in a forthcoming series, explains why AI reaching gold-medal performance at the International Math Olympiad did not mark an AGI moment as many predicted, contrary to expectations Patel voiced three years earlier. The conversation reveals that AI systems like those from DeepMind solved IMO geometry problems in 19 seconds through brute force rather than creativity, yet still struggled with combinatorics problems requiring novel insights. A central theme emerges around the challenge of training AI to generate genuinely novel mathematical concepts rather than just proving theorems. Sanderson traces this through the historical example of Galois and group theory, whose revolutionary insights took nearly 100 years to be recognized as valuable because the verification loop for breakthrough mathematics can span generations. Patel argues that AI's mathematical progress stems not just from verifiable outcomes but from the ability to parallelize unlimited attempts in containerized environments, a property unique to math and coding. The pair discuss whether AI will eventually make connections between disparate mathematical fields, citing the famous Montgomery-Dyson conversation that linked number theory to quantum physics. Looking forward, Sanderson predicts human mathematicians will transition from theorem-proving to curation roles, helping society navigate vast landscapes of AI-generated mathematics. They explore why current AI systems remain surprisingly weak at theory of mind, writing quality prose, and escaping their training context, while excelling at technical explanations and cross-field connections. The conversation concludes with practical advice for students considering mathematics careers in an AI-dominated future, emphasizing the enduring value of teaching, curation, and understanding where mathematical work creates genuine economic or social value.
