Here you go, Akalabeth. I'll provide a list of possible genetic fixes, and you can explain to me how technology would do a better job of correcting these problems.
1. Move retinal arteries behind the retina instead of in front to prevent many causes of blindness.
2. Remove wisdom teeth to prevent brain abscesses, empyema, and meningitis.
3. Slightly lower the position of the larynx. Helps with choking.
4. Alter the odontoid process in the spine; a simple ball-and-socket joint instead of a peg here would prevent a lot of paralysis injuries in whiplash.
5. Strengthen hip joints, which are still optimized for quadripedal locomotion - that's why the hip joint so frequently degenerates with age. You'd need to do some canny designing to pull this off.
6. Intelligently re-engineer the knee joint while you're at it. It's also still optimized for quadripedal life, and it's way too weak.
7. Redesign the foot so we're no longer walking on our wrists. I'll leave the specifics to the structural bioengineers!
8. Weave the plantar nerves in the foot into the bone structure so they're not crippled by arch collapse.
9. Redesign the median nerve in the wrist so it's no longer damaged by each wrist flexion. Improve ligamental shielding.
10. Move the ulnar nerve to the inside of the elbow; we're not horses, so why is it still built like a horse's ulnar nerve?
11. Reengineer the brachial plexus and add protection to prevent the destruction of the nerves there by certain forms of pressure.
12. This might be a contentious one, but the placement of the rectum, urinary tract, and vagina in females is poor and prone to infection. Needs a bugfix!
13. Remove the appendix.
14. Prevent progressive dilation of veins in the legs during posture change to reduce the risk of death by blood clot.
15. For god's sake, move the vital cranial nerves and carotid artery structure farther from the nose, or protect it somehow! We shouldn't be dying of sinus infections that get into our vital nerve and blood pathways. Similarly, move other cranial sinuses away from the middle ear!
16. Prevent chordoma and gill-type birth defects; they're a product of old evolutionary structures that grow and then vanish during fetal development, for no real reason.
That's my shopping list! Some of them are easy fixes, some would be hellishly tricky, but I'm sure the same human ingenuity that built the space shuttle can figure it out.
Hibernation as it exists in nature is a involuntary part of an animal's life cycle which is dictated by the seasons. So how is it that humans or any creature will be able to biologically hibernate at will.
HIT injections. Or an internal gland under voluntary control. Easily accomplished - there are dozens of organisms that can voluntarily alter their biochemistry like that.
Sorry for not answering that earlier. Satisfied?
Sorry if I ignored you, but I haven't exactly been systematically dismissing your points. It was an honest oversight.
I really dislike your style. I don't enjoy these debates when they turn so personal.
