To the Members of Congress, Regulatory Agencies, and Policymakers, We write to urge restraint. As you consider new rules for artificial intelligence, we ask you to resist the instinct to regulate first and understand later. The history of transformative technologies — the printing press, electricity, the internet — teaches the same lesson every time: premature regulation calcifies incumbents, chills experimentation, and rarely protects the people it claims to serve. Innovation needs room to fail.
