Genetic enhancement in humans isn’t likely around the corner, but it will be pretty impossible to avoid its path at some point in the future even if you disagree with it, the way the online world is currently almost unavoidable. A brief passage from Nick Bostrom’s Superintelligence about how designer babies may sway people, even countries, to fall in line:

“Once the example has been set, and the results start to show, holdouts will have strong incentives to follow suit. Nations would face the prospect of becoming cognitive backwaters and losing out in economic, scientific, military, and prestige contests with competitors that embrace the new human enhancement technologies. Individuals within a society would see places at elite schools being filled with genetically selected children (who may also on average be prettier, healthier, and more conscientious), and will want their own offspring to have the same advantages. There is some chance that a large attitudinal shift could take place over a relatively short time, perhaps in as little as a decade, once the technology is proven to work and to provide a substantial benefit.”
