2030: Theories for Everything Claim

Tudor Achim is the co-founder and CEO of Harmonic, a startup working to solve one of AI’s hardest problems: mathematical reasoning. In July 2024, Harmonic achieved gold-medal-level performance on International Math Olympiad problems alongside systems from OpenAI and Google DeepMind—but with a key difference: every proof Harmonic submitted was formally verified. Tudor's path to Harmonic wound through competitive piano, computational biology, and autonomous driving. He studied at Carnegie Mellon's music preparatory school, worked on machine learning at Quora, briefly pursued a PhD before dropping out, and then co-founded an autonomous driving company, Helm.ai. Harmonic's core product, Aristotle, uses reinforcement learning and the programming language Lean 4 to solve problems and verify solutions.

In our conversation, we explore:

• Why Tudor believes math is the fundamental toolkit to understand the world
• How Harmonic uses hallucinations as a feature, not a bug
• How Aristotle works and the applications beyond pure mathematics
• The reinforcement learning process that lets Harmonic generate synthetic training data and solve problems humans have never attempted
• Why Tudor believes AI could surpass human mathematicians on specific tasks within 2–3 years
• Why the future of mathematics looks more like GitHub than academic journals
• The alternating pattern between intellect leaps and data leaps throughout scientific history
• How studying piano under an extraordinary teacher taught Tudor discipline and the value of sticking with hard problems
