Not everyone wants a purpose, many people who have purposes imposed on them by parents or other authority figures later reject them, and not everybody who does want a purpose thinks of it as a search.

Purposes are tools humans use to give their own lives meaning, if they desire. Purposes should serve humans, not the other way around.

There's no indication that someone's genetically-specialized vocation would be something that that person would personally be interested in pursuing. There are numerous counterexamples of a person's choices in life being orthogonal or even entirely opposed to their parents' hopes and desires for their life.

I wouldn't be that into assassination as a vocation even if I had superpowers that made me an extremely good assassin, for example.

It sounds like you are very much in the party of nurture over nature. Either could result in a person "being into" something. You are taking your genetics and your upbringing and projecting them onto future scientific possibilities, and I don't think that makes much sense.

What if you sequence the great computer scientists and average ones and find some genes that really make a difference? What if you sequence sociopaths and discover a series of genes that correlate heavily with it? Sexuality, flight or flight responses, physical aptitude, mental aptitude.

We've spent millennia doing a less advanced form of this on dogs, can you honestly say a lot of these dogs we've bred for specific jobs aren't "into them"?

> It sounds like you are very much in the party of nurture over nature.

No, this entirely different to that. I'm saying that a person's physical attributes are orthogonal to that person's personality. I'm not discussing if their personality is a result of nature or nuture, just the fact that if you're, for example, physically predisposed to, say, being able to grow large muscles, that has no bearing whatsoever on whether or not you are personally interested in, say, competitive weightlifting (regardless of whether or not that personal interest (or lack thereof) is a result of nature or nuture).

The fact that you are predisposed to be able to grow large muscles is obviously nature; the circumstances surrounding whether or not you actually do grow large muscles is open to the nature/nurture debate, as well as the psychological manifestations that might lead one to engage in (or avoid) bodybuilding, competition, et c.

There's no real conclusive science for what you're proposing. The body could be impacting the mind and altering one's personality but we haven't learned enough about the brain to really know for certain. Opinions on this topic are likely from anecdotal experiences and not real science.

I've thought about it and there are for sure small physical things I'd love to change from birth to benefit my sport/hobbies.

But the problem is parents would be making that decision. Or in this case a dictator's military haha.

There are already hover parents living vicariously through sports, music, chess whatever.

I can imagine this going to extremes with parents making these forever physical decisions.

Elite athletes can chose to endanger their health for the sport they love.

But I'm not sure about the ethics of a parent deciding to say give lower resting heart rates/higher vo2 max with cycling in mind, even though it could be deadly slow.

What if they aren't interested in, or worse, resent their "purpose," but can't change it due to some societal and genetic pigeon-holing? That sounds worse than searching for a purpose for myself, tbh.

That's horrible. I think you don't know what a meaningful life is.

Almost nobody does, at least today. Some offtopic. The reverse side of the dollar bill depicts a small pyramid with an eye on it. This symbol is a pretty clever summary of our civilization. The eye means the human mind that connects a small upward facing triangle at the top - the spirit, with a heavy structure at the bottom - the matter. The upper triangle is small because today people barely recognize its existence. The mind tries to figure out which side it belongs too and often it gives up and identifies oneself with the matter. The "purpose" from the comment above is the pinnacle of this thinking: the mind decides that "since I really belong to this two legged biomachine, my purpose must be same with that machine's".
