I know people who work with CRISPR, or at least I used to. Can’t stand to associate with them anymore. They are NOT the same people they were so many years ago. Gene splicing, selecting traits, if you can imagine it, it can be done and most likely has been…the Human Genome Project opened the door for them. I also know people who worked on that. They have regrets for being a part of it… knowing what their work has led to. 😢
