We’ll just all assume that every person who gets this would make themselves early twenties with flawless skin, perfect organs, appendages and functionality, and no excess weight.
My question is, would you change yourself from your genetic baseline, and if so, how?
Within the realm of existing biology, I would take the ability to rapidly change colors like cuttlefish and octopuses. More efficient skeleton/muscle to be as strong proportionally as a monkey. Better eyesight and color vision (birds of prey).
Beyond that into superhero/magical, omnipotence is the catch-all that makes everything else moot. I probably wouldn’t hit that button though.
So this means you are squarely into transhumanism right?
The only people I’ve met who called themselves transhumanists were straight up barmy. I don’t know enough about the actual movement to claim association with it when the small sampling I have indicates “hell, nope”.
