You found the future, Biology is a completed engineering corpus. What do you modify about yourself?
Let's say there are consequences where all genetic alterations are difficult to sandbox and largely irreversible during an extended, but still finite lifetime of around half a millennia.
Rules:
changes will be passed down to your offspring
any change may make you sterile, but large changes will always make you sterile
alterations are most effective when done under the age of 20 and do not fully manifest for decades
if you screw up your code it might be deadly
biology as an engineering corpus is several orders of magnitude more complex than computer science was in the 21st century – screwing up is very easy
any adaptation present in evolutionary life is technically possible to someone dumb enough to try and brilliant enough to pull it off
Vagina dentata (Latin for 'toothed vagina') is a folk tale tradition in which a woman's vagina is said to contain teeth, with the associated implication that sexual intercourse might result in injury, emasculation, or castration for the man involved.
Give myself the ability to recover from more severe injuries given a good space of time to uncripple myself.
Extend my lifespan. Maybe just another 50 years, I'm not too greedy. But with relative youth. I don't want to lose my good looks to age any sooner than I have to.
Can I just pay some smart person to do it for me? I couldn't handle my 100 level CS courses 20 years ago, I'm definitely not making updates in production on my own body. Oh who am I kidding I couldn't afford to pay someone that smart.
Self-deprecation aside, I don't know of any non-human features I'd want, I'd just wanna OC my metabolism for a while.
I'm growing two huge demon horns on my head and you can't stop me! Also a dragon tail probably some scales and gills. Now am I asking for too much with a bio luminescent uh... Penis?
