summarizing my take aways from reading Gwern's post on embryo selection for intelligence on 2024-07-20
Possible today:
- IVF Simple Embryo selection - around 5 eggs are extracted from a woman and fertilized. Each resulting embryo is biopsied for a a few cells, which are sequenced, to determine a polygenic score (some scoring for genetic desireability) for each. The best embryo is implanted. Note that there are common complications; embryos may die in storage, the embryo may fail to implant, etc. The process costs on the order of $5k.
Possible in the future, Gwern describes a range of possible future developments. I will highlight four:
- Massive Multiple Embryo Selection - eggs are extracted as before (or if we figure out pluripotent stem cells well enough to make eggs from skin cells, do that). The extracted egg cells are "replicated hundreds of times" to original eggs. The resulting eggs are fertilized to create a few hundred candidates, of which the best is implanted. Since bi
