Here is a thoughtful essay that deals with some of the potential issues: https://quadrant.org.au/magazine/2015/05/eugenics-ready/ https://quadrant.org.au/magazine/2015/05/eugenics-ready/ He makes a distinction between "negative" eugenics (removing genetic disorders & decreasing mutational load) and "positive" eugenics (selecting for intelligence, appearance, personality, and other desired traits), and considers what will happen if either of those is adopted by either a minority or a majority of the populace. At a high level, the biggest concern is if you have a minority of the population practicing positive eugenics, because it leads to a runaway "rich get richer" situation. If you think income inequality is bad now - it will only get worse.
