Is such an outcome so terrible? Yes, it will be unfair if some humans are smarter, stronger, and healthier than they otherwise would be. But these people will be a massive benefit to the rest of humanity.[1] We'll end up with smarter doctors, lawyers, scientists, and (gasp) politicians. If you think at the margins (would it be better if people were smarter or dumber, on average), the answer is clear: Human enhancement is almost certainly a good thing. Anyone who says otherwise is in the same boat as those who worried about the implications of vaccination, antibiotics, and stem-cell therapy. These technologies do have downsides, but the benefits are so much greater that we're all glad they were invented. Personally, I'd rather live in a world where more people were smarter than me. While it would diminish my own status, humanity would be able to solve more of its problems. Finally, you assume that enhancement technology will remain expensive indefinitely. Historically, new technologies have gotten cheaper over time. While not everyone will be able to afford enhancement at first, it seems likely that it will follow the same trend as Internet access, smartphones, gene sequencing, and countless other technologies once reserved for elites. 1.
