Why AlphaFold Didn't Solve Protein Folding — Pushmeet Kohli, Google DeepMind & Sal Candido, Biohub
From the Bitter Lesson of AI scaling to the unsolved mysteries of protein folding , Google DeepMind’s Pushmeet Kohli and Biohub’s Sal Candido are rethinking what it takes to build AI that truly understands biology. In this special panel moderated by Brandon Anderson , they explore why AlphaFold’s breakthrough was only the beginning , why scaling compute and data alone won’t solve biology, and how the next generation of AI models could transform our understanding of proteins, cells, and human disease. We go deep on the future of AI-driven biology : finding scaling laws in biological data, the tradeoffs between scientific intuition and general-purpose architectures, why protein structure prediction is far from solved, and what it would take to build predictive models of living systems. Pushmeet reflects on the lessons behind AlphaFold , the limits of human interpretability, and whether future frontier models could understand other AI systems better than we can. Sal explains why protein language models may already contain scientific knowledge we haven’t unlocked, how biological modeling must move beyond individual proteins, and why achieving Biohub’s mission to cure all disease requires thinking in terms of 10x breakthroughs rather than incremental improvements. We discuss: * The Bitter Lesson for biology : why scaling compute and data isn’t enough * Why finding the right scaling law matters more than blindly increasing model size * How low-quality metagenomic data can improve protein language models * Why AI researchers optimize for available data instead of the most important scientific problems * Lessons from DeepMind on balancing modeling, data generation, and scientific expertise * Why building a virtual cell requires fundamentally different datasets * AlphaFold’s handcrafted architecture and the role of scientific intuition * Why good data matters more than simply having more data * Inductive biases, scaling laws, and the future of specialized AI architectures *
