I think the end game in genetic manipulation of living beings will look a lot different. For example, there is a lot of research going into so-called in-vitro gametogenesis. Basically, production of sperm and ova from stem cells. You can already produce fertile ova from blood cells in mice. In humans, the process is a bit more challenging and will likely require artificial ovaries, but there does not seem to be any really major obstacle in the way. It is mostly technical stuff to be mastered. Thus, somedays in the future, 2040 or 2050, you may simply walk into an IVF clinic, have your blood drawn and 1000 healthy eggs produced out of it. (It might actually work for males as well - a boon for gay pairs.) 1000 healthy eggs mean 500 viable embryos. Choose one for implantation, or perhaps two. (Or perhaps artificial wombs will be already available.) At this moment, people will start to choose according to criteria that other people will abhor. Simply because they will be able to. And all of this technology is double use. Much like firearms or computing. You can prevent untold horrors or you can unleash them. I respect your idea that some technology should be taboo, but I don't agree with it, and I think it is fundamentally unviable in a world of nearly 10 billion people and 200 nation states, which is becoming increasingly multipolar. The next Cold War will have a substantial biological component. See also: Covid-19 and its effects on the world.
