Randall Parker has a list of consequences when the cost of individual gene sequencing comes down (as it inevitably will). I found this one interesting:

Discovery of genetic variations that contribute to appearances such as genes for eye and hair color, complexion, hair texture, facial shape, and other attributes that contribute to visual desirability.

Physical desirability is a two-way street. We are bred to appear desirable, but we’re also bred to view desirable people as desirable. I wonder if some people might not figure out how to rearrange their genes to change what is desirable to them? That’s probably a much tougher problem, though.
