I uploaded I.J. Good’s classic paper “Speculations Concerning the First Ultraintelligent Machine” to the Accelerating Future server because I saw that mainstream sources were linking it at the Internet Archive, which is just silly.

In the paper, Good writes:

The survival of man depends on the early construction of an ultra-intelligent machine.

I don’t doubt it. But be careful how you construct it, or the ultra-intelligent machine will end the survival of man.
