I for one don't think we should put so much value on intelligence. Maybe even health. There's no reason for humans to try to play God. It's not like we did such a good job on Earth. Correlation is not causation. So humans have more intelligence than chimpanzees. This might be explained by the difference in DNA. So do we really need to tweak this little piece of DNA? Is that what makes us intelligent? What if by increasing intelligence, we introduce bugs in our genetics? I have read Nick Bostrom's books. Some of his ideas make sense. But he obviously likes exaggerating and getting attention. So this email doesn't surprise me. We should beware false prophets who tap into our desires for a better world. So easy for them to introduce counterfactuals when they do that.
