Earlier quoted context omitted.
Which implants and prosthetics currently exist that are such that a median person would want them and as a result would become super-human?
As was mentioned in another comment, breast augmentation and other forms of body modification in the context of influencers, broadcasters, actors, models, etc. Prosthetics may not quite be there yet, but do you seriously think they won't get there? Military is actively investing in exoskeleton R&D. Whether it's currently accessible to the median person is sort of besides the point.
It might happen in the future, but it's worth considering that a powerful prosthetic limb or exoskeleton that is superior to the biological version in every way makes both the disabled person and the perfectly healthy person equally superhuman.
