Wealth already causes a large division in biology. Although as of now it's still confined to the phenotype of humans (better nutrition leads to better physical development and higher performance, mental or physical). However if recent advancements in biotech continue this might soon affect the genotype as well and that's where I believe we should draw the line. I don't think there is a single society which can cope with a strong heterogenity in the genotype. In the past humans have killed each other based on different shades of skin color - imagine what would happen if they were different down to the bone marrow.

Governments need to step in early and create two exclusive lists for approved genetic mutations. One for which every member of society can opt-in free of charge and a second list of mutations which can be purchased at your local gene shop. Example for the first list would be improvements to your cognitive abilities and health in general. On the second list should be mutations, which are mainly concerned with aesthetics (change skin color, shape of ears, etc.). Ultimately there needs to be a broad political discussion which mutation belongs on which list - and as societies evolve those two lists will change.

What do you think about the effects biohacking will have on the diversification of people? Will we further isolate ourselves based on our interests? If I want to be smart and enjoy solving problems I will take nootropics while many also enjoy being strong and will supplement their selves with vitamins and whey. Biohacking is already a reality. Bud do we want to live in such a society?
