All right, I can be serious.
I mean civilization being wiped out by the Sun's death wouldn't be good right?
Hmmm ... the Sun is about halfway through its life-cycle on the main sequence. That gives us about five thousand million years before the Sun expands into a red giant. Multicellular life on earth has been around for about five hundred million years, just to put these things in perspective. Current evidence suggests that modern humans have been around for about two hundred thousand years. In the United States (just to give one example) nobody has any real idea about how to to keep Social Security going for more than about twenty
I don't think we need to worry about civilisation ending because of the Sun's death for a while yet. But yes, on the other hand, you're absolutely right. The human species as is
is not conducive to the stewardship of the only planet that we've got right now. Nevertheless, I wouldn't worry too much about the planet. Worry more about the species. It's more likely that the planet will shake us off like a dog shakes off a bunch of fleas than it is that we'll render the planet uninhabitable.
And, if you're hoping to save the species and climb up the Kardashev scale of levels of technological development of civilisations, I think you'll be dissappointed - not that you're likely to live long enough to find out even given various antisenescence technologies which might come along while you're still alive.
It's really not a question of whether there will be genetically engineered humans; it's more a question of when, by whom, and to what purpose.
Given what we know from recorded history (granted, not much information about a pretty short period of time, but it's all we've got), I don't think we're going to get people who are genetically engineered to be more intelligent and more conscientious. From what I can tell, we're more likely to get:
1) Reversal of male pattern baldness, 2) Breast augmentation, 3) Increased athletic abilities, 4) Fewer wrinkles and blemishes of the skin, 5) Long, luxurious hair which shines and flows, 6) Whiter, more durable teeth ... I think you must get my point.
I get that you're the kind of person who wants to improve the human condition and ensure the future of the species. Just remember that most people don't care at all about the future of the species or space colonization, and have never heard of the Kardashev scale.
Sure, you can go around like Ray Kurzweil, writing books and giving talks. I just wouldn't get my hopes up too much.
Just so that you know, I never look at Youtube links anymore. Go ahead and post them, just don't expect me to respond to them.
Finally, as a side note, why do you keep changing your nickname/avatar? I really am just curious. It doesn't bother me, though some people might find it confusing.
