> because genocidal movements are corrupt well beyond the "power of science."
Science was central to the genocidal movements in the US and Germany. In many ways, science was the cause of the genocidal movements. Eugenics was a scientific movement championed by scientists. What changed wasn't science. It was culture and politics that changed. The horrors of the 20th century led philosphers, politicians and ordinary citizens to lose their blind faith and trust in science and progress.
The rise of science and social darwinism of the early 1900s is similar to rise of AI and technocracy. Hopefully we won't as foolish to place blind trust on it and history doesn't repeat itself.
