This week, Dean and Tim talk to Charles Yang, a former staffer at the Department of Energy who now writes the Rough Drafts newsletter. Tim has written extensively about AI in science, concentrating especially on the potential of AI to transform materials science. His work has focused not just on models, but on building robotic, “self-driving” labs to accelerate scientific research. The conversation touches on the latest AI advancements in science, how AI models do and do not help scientists, and what might be coming next.
