The Paradox of Open-Weight Models: From Protein Folding to Geopolitics

When Dario Amodei says he "doesn't oppose open-weight models but fears Chinese AI," a fundamental contradiction is laid bare: How do we prevent technology from being used by adversaries for military or surveillance purposes without hindering scientific progress? As a researcher who uses AlphaFold2 and ESM-2 daily to predict protein structures, I know firsthand the revolutionary impact open weights have had on bioinformatics—without Meta's open-source ESM series, we couldn't rapidly screen mutations in small labs lacking GPU resources. But Amodei's concerns aren't unfounded.
