Mate selection based on personality and physical attributes is totally natural and leads to good outcomes while incentivizing good personality traits and physical health. But selecting an embryo based on predicted characteristics is totally unnatural, leads to unknown outcomes and incentivizes everyone else to select and edit their babies so that their offspring remain competitive. This leads to a dystopia in which natural humans become an underclass and people are coerced into using these unnatural processes that may have unforeseen negative consequences and can be abused, for example by a government wanting a more controllable population.
