"Just as nuclear scientists developed norms of ethics and best practices that have so far helped ensure that no bombs have been used in attacks for 70 years, AI researchers, he urged, should embrace a similar ethic, and not just make cool things for the sake of making cool things."
That said, attributing nuclear disarmament solely to "norms and ethics" of scientists is pretty reductive on the part of the author. In fact there were large nuclear disarmament movements in Japan, UK, and the US after WWII. It was as much public pressure as anything that lead to the Partial Test Ban treaty in '63. Similar movements in the 80's led to further reduction in arms. One million protestors marched in Central Park in '82, protesting the nuclear arms race. That's a staggering number and indicative of how widespread and popular the nuclear arms reduction movement was at the time. Comparing that to the "Anti-AI" movement—which just about everyone would agree is pretty niche—is problematic at best.
