This piece, published last week, lands right in the middle of a fascinating debate about the future of scientific discovery. For years, the incredibly complex chemistry behind life-sustaining enzymes like nitrogenase has been held up as a problem only solvable by future quantum computers. But what if we don't have to wait? One chemist, Garnet Chan, and his team just made a breakthrough using purely classical methods, pushing back on the idea that these problems are out of reach until quantum hardware arrives.
