You know nothing of evolutionary biology do you.
Well, statistically speaking in only about 15 generations or so, there's a good chance not a single gene you have inside you will be in any given desendent. Kind of depressing really.
Do you care that your kids look like you? That's what it comes down to in the end.
Everyone does, actually. Its a genetic imperitive.
Every time a generation occurs the number of genes, and the similarity to you, decreases. Eventually you'll blend in with the white noise that is the entire genetic pool of humanity. How is this immortality, in any sense of the word? I don't see it as being any better or worse than passing on your ideas and values.
Well, to be fair, if your genes are superior, you can get them passed on more. Though that assumes natural selection continues to function on humanity.
Hence my mass genetic engineering! I will leave my mark on everyone forever! Mwahahah!
Plus I plan to live forever, so there is that too.
I guess the question really is... how important to YOU is it that a kid has the same patterns of molecules as you do, for a few generations? Unlike the genes themselves, or more primitive animals that are bound ONLY by instinct and genetics, we have the complexity required to make that call.
Well maybe. We don't really know to what extent our genes control us. We do know that certain traits are highly heritable. Intelligence, for example, is more than 50% heritable - some studies indicate it might be as much as 80%. And intelligence has an extremely large impact on how you behave.
A lot of complex behavioral traits are probably in part genetically moderated.
I do love to spite my genes, but I know that I can never really be sure that that very urge isn't being given to me by my genes themselves.
I think that my instincts compel me to have sex, not to reproduce. Does a wild animal KNOW in it's mind that the act of mating will cause it's genes to carry on? I think it's just programmed with an urge and acts on it. How are we different? I don't think that wanting to reproduce is a fundamental instinct, because it needs an abstraction, a causal connection between events to work.
I disagree, actually. I'm pretty sure that animals do in fact understand that sex = babies. Its bred into us to expect that having sex makes babies.
What I'm saying is that genes disappear, ideas disappear (at least most of the less important ones), there isn't a true immortality for us. I don't think genes are much (if any) better than ideas in this regard.
You could build a giant mountain out of rock. It worked for the Ancient Egyptians.
Too many people in the world. Gotta think of the future, y'know? So I say no, I don't want children.
Here's a scary thought though:
Of all the complex behaviors which may be genetically moderated, it is VERY likely that our desired family size is actually very directly controlled by genetics.
That is to say, ironically, by you not having children you're very likely making those who want to have too many children take up too much of the human gene pool.
So everyone who thinks it is irresponsible to have children due to overpopulation should have more children, because the people who ARE irresponsible will have them anyway and we don't want them to keep doing it, and the only way to fight back is genetics.
Or you know, genocide. But you guys never let me throw people in ovens anymore
