That's an amazingly ignorant comment. First of all, the better evidence is behind the idea that currently observed high human IQ, when the "g" factor is factored into consideration, consists mostly just of luckily lacking deficiencies in function that other human individuals have. In other words, the centuries-long factor-analytic approach mostly suggests that high-IQ individuals luckily lack "general stupidity," but still are subject to hard limits on human cognition (Mackintosh, IQ and Human Intelligence second edition 2011, pages 155-156).
And the hard limits on human cognition are intractable, and actually illustrated by the article kindly submitted here. Psychologist Keith R. Stanovich points out in his book What Intelligence Tests Miss that even very high-IQ individuals (studied in studies of members of high-IQ societies) are still subject to most human cognitive biases, and they can be MORE subject to delusional beliefs than members of the general public because they can make up elaborate rationalizations for anything they choose to believe, including a belief in superintelligence.
I doubt the statements in this article also because there is a long line of research that goes back to before when the article author was born on selective breeding of mice and rats for high intelligence in their behavioral context. (One kind of test of intelligence given to rats and mice is running through mazes to find food.) Since before the author was born, there have been purebred strains of "maze-bright" and "maze-dull" rats that have been tested by psychologists. Now that there are gene technology methods in animal research, there are transgenic mice with knocked-out genes and added genes, and the author significantly fails to mention any experimentation in animal models that shows that his speculation is likely to become true.
The Wikipedia article on IQ classification adequately cites references to demonstrate that the IQ scale is strictly ordinal, so indeed a notion of "IQ 1000" is meaningless.
If you'd like to read a more thoughful article on genetic influences on human IQ, by a researcher who has been closer to the research for longer and who has published in better journals than the author whose essay was kindly submitted here, see Wendy Johnson's article "Understanding the Genetics of Intelligence: Can Height Help? Can Corn Oil?"[1] which has an excellent review of decades of research on genetics and on human intelligence.
