Yeah, I'm amazed that so many commenters on HN think that the technology, or even our understanding of things like "smarter & better looking" is anywhere near this level of sophistication. The sentence that really stood out to me was: > In the years since He’s revelations, researchers have uncovered further concerns about the use of CRISPR–Cas9 in embryos, including that it can shuffle large segments of chromosomes. There are a number of horrible genetic diseases, including Huntington's Disease, that do not present until later in life; for Huntington's Disease it typically presents when someone is in their 30s or 40s. We don't know what shuffling chromosomes might do. There's a very real possibility that if there was widespread adoption of CRISPR to make children smarter and more beautiful, it would could with the side effect of condemning their bodies and/or minds to fall apart in their teens, 20s, or 30s. Animal models won't tell us this. We'll only learn the true consequences over time. This is one of those situations where "move fast and break things" is just wrong.
