I don't understand why you think this is an argument. We've been messing with the gene pool of our food for thousands of years, and I'm yet to see anything other than benefits to that.
EXCEPT that we can never, ever STOP tinkering. We can increase crop yield, we can increase resistance against certain diseases or climates, but we can not leave these things alone lest they get wiped out due to a new attack that hits these plants where they are weak. Now, in plants, this is easy to do, and even beneficial for us, but do you want to do the same things with humans? Please address the issue of how to do a large-scale genetic engineering program on humans
so that it is controllable within the average humans planning horizon. You need several generations of engineering before you can see benefits, which means that you'll have to wait 20 or more years before you can be sure your tinkering has actually worked, and EVEN THEN, you can't be sure it did because you cannot raise lots of humans in a controlled environment.
I'm not saying that an efficient "genetic program" would be stupid enough not to understand the necessity of keeping banks of genes stored somewhere. If there are "bugs" in the process, correct it. As I SAID IN THIS THREAD, you'd have to manage the process, adapt, etc.
But why spend all this time and effort managing something that is able to self-correct?
Where did I stated the term SAFELY? I even said dangerous. I also fail to see where our ignorance of all these processes created an agricultural holocaust. You don't need to understand the whole process if you have simple algorithms and reliable feedbacks. You speak about "long term" which is a good point, but then again this point also has the other side of it.
What? Simple algorithms? Reliable feedback? When you're messing with lifeforms as complex as humans? Again, the average generation in humans is over 20 years. Humans cannot manage experiments on such timescales reliably.
What if you don't tinker with the gene pool? There are also unintended, and possibly dangerous, consequences to that. Because of our sucessful health programs in the world, the pressures against genes that cause disease and deaths in the young, etc., no longer apply. The gene pool will inevitably "diverge" and occupy that landscape of possibilities as well. Which in turn will create a lot of finantial hurt in the health system.
(Albeit, I'm an optimist on that front, confident that any evolutionary drift towards such problems will be countered by technological advances).
Let me remind you, most of the conditions that you want treated via gene modifications can also be treated safely and reliably via medication. If I would have to choose between taking pills, and undergoing genetic modifications, I know I'd choose the pills, because I know that we don't know all that much about how all this gene stuff works together.
The hubris that calls itself mankind and civilization, a whole process that altered the face of the earth in infinitesimal time scales compared with the hundreds of millions of years of evolution. I find it marvelous. And if mankind is to die out like the 99% of the species ever lived here, I'd rather risk it and have it with a bang, than just cowardly die out in a whimper.
Personally, I'd rather leave off the banging and continue living, but that's just me I guess. Look, your whole argumentation seems to be based on technological optimism. Which is good, any SF fan has that in spades, myself included. But where is the skepticism you were so proud of in that other thread?
You honestly believe we won't mess with our own genes within a hundred years?
I'm quite sure we will. However, I am equally sure that, for the reasons outlined above, it will not be something that will be large-scale. Individuals may opt to have their genes modded, but entire societies? Not in my lifetime, I think.
