One of the problems of arguing with you, Bat, is that your arguments are almost alway really messy. Jumbled together. That leaves the guy on the other end with no choice, if he's to make a pertinent and considerate counter- or pro-argument, but to sort it all out before ever getting to his own point. Even moreso when that other guy finds the arguments to be swarming with false notes. And since I'm moving right now and might not be online for 48h after the move, I can't say much right now.
Except a few brief things:
It's inaccurate to reduce it all to arrogance. IMO this says more about your own POV and personality than anything else.
There will always be people who fail. For whatever reason. Stifling one's progress because another is failing, sometimes purposedly, is disingenuous. Someone has to lead the way. "Lead, Follow, or get out of the way".
"The cross over point in time. When different humans of the same generation across the world live in such contrast that one lies in a field with no legs from a landmine, wondering what the hell it's all about and another sits there in such comfort that they spend time dreaming of what they would do if they lived forever in perfect health."
This is typical of your arguments on this type of subject... An appeal to emotion.
On another topic that relates to humanity's savage way of treating each other and better ways of repairing and increasing our vulnerability to death. Surely with how humanty lives this technology would only serve to make war last longer and weapons do more damage. Not that the arms race needs any fuel right now..
There is no perfectly safe life, no perfectly safe technological innovation. Saying that "surely" the progress of tech will mean more war, etc, is completely biased and subjective.
When I'm done moving I'll sort thru the OP.
