I did not say 1000 times smarter. I said 5+ standard deviations. John von Neumann had an IQ 5+ SD above the mean. We know this phenotype is possible. It is not science fictional to think we can raise the average to at least his point. In animal breeding we increase traits by much more than 5 standard deviations all the time. Iterated embryo selection and/or direct genetic engineering will be able to do this. It breaks no physical laws, it is in concert with what we have already observed and our understanding of cognitive genomics is getting to the point that it is becoming increasingly obvious to anyone paying attention that we will be able to select/edit for intelligence comparable to John von Neumann. Look at the "Known for" section of his Wikipedia page to see what such people will be capable of: https://en.wikipedia.org/wiki/John_von_Neumann https://en.wikipedia.org/wiki/John_von_Neumann "That sounds vaguely like a science fiction story" is a very poor heuristic for determining if something is possible.
