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.
Awh, the burden of responsibility!
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?
How many times do I have to repeat the things I have stated, and paraphrasing you now, "IN THIS THREAD" that such kind of human selection would be dystopian? It's quite literally a
nazi program we are discussing here. My point is that it "works", not that we should "desire it".
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.
Genetic tinkering will be only done when it benefits the users directly, or their offspring for that matter (Gattaca, etc.). It will create a swarm of ethical problems, and I'm not so sure we will solve them in a way I consider satisfactory. It will happen.
But why spend all this time and effort managing something that is able to self-correct?
How can something that has stepped out of any selection pressures is "able to self-correct"? Even if true, nature is still very slow. We always like to make it faster. Analogically, "why should we build cars if we are able to walk on foot?"
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.
Yeah, many people talked in the same vein about antibiotics and pesticides. And it was true for some time: we didn't know enough about it. We even banned DDT for a stupid reason. It turned out that the banning was just half stupid: there are problems associated with the spamming of too much of these chemicals.
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?
My skepticism is towards the notion that "gene selection in humans is impossible".
If the motion was that "genetics will be wonderful" I'd be proudly skeptical of that too. As I said, lots of dangers lurking in the landscape of possibilities there. But the priiiiiizee...
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.
Yeah, not in our lifetime. Unless the rapture for the geeks comes first. hehe.
