Biology and materials science are shifting from observation to engineering. Liam Fedus told No Priors that AI’s bottleneck is the physical world. Trained on unreliable scientific papers where material properties vary by orders of magnitude, AI models reproduce human confusion. Fedus’s startup, Periodic Labs, addresses this by creating closed-loop systems where AI directs robotic labs to run experiments, generating its own high-fidelity data.
This transition makes AI not just a tool for prediction but a new type of scientific object. On the Dwarkesh Podcast, Michael Nielsen argued that models like AlphaFold are high-dimensional artifacts requiring “interpretability archaeology.” They contain embedded knowledge we must excavate, changing the scientist's role from theorist to excavator.
“Science ultimately isn't sitting in a room thinking really hard. You have to conduct experiments to interface with reality.”
- Liam Fedus, No Priors
Colossal applies this engineering mindset to biology. CEO Ben Lamm told Moonshots the woolly mammoth project is a stress test for a platform. The goal is a synthetic biology engine capable of spinning out companies tackling everything from plastic degradation with AI-designed microbes to artificial wombs. The AI leap is stark: where genetic editing was 40% efficient three years ago, Colossal now achieves 90% efficiency on hundreds of simultaneous edits.
This design-based approach confronts nature’s inherent disorder. Radiolab featured a 30-year experiment where a sealed barrel of seawater never reached ecological balance, its species populations booming and crashing chaotically. If there's no natural equilibrium to restore, the task for AI-driven conservation becomes managing preferred states of chaos.
“Actually, chaos is a system which is high predictability on the short run, but cannot be predicted in the long term.”
- Alisa Beninca, Radiolab
The shift is attracting a new kind of researcher. Fedus noted that physicists, bottlenecked after the Higgs boson discovery by slow, massive hardware projects, now dominate AI. They treat neural networks as physical systems to be measured. This principled thinking accelerates the move from digital simulation to atomic rearrangement, promising a materials revolution akin to the agricultural leap. The frontier is no longer just understanding nature, but remaking it.
