Slightly-misleading TLDR: Iterated embryo selection is sort of test tube reproduction and selectiong. If you can create gametes from stem cells, then create many more embryos with these gametes and then score each embryo, repeating the process selecting for those that have the best genetic correlates of cognitive ability, you can perform the equivalent of a 2000 year eugenics experiment in a test tube in about six months. You could potentially get far, far higher IQs than 160.

Prerequisites for this are cheap-gene sequencing, very, very large databases of genomes tagged with their donor’s cognitive measures, and advances in human stem cell research.

What is your time estimate for these prerequisites?
