>>9858258>Because of the simple function of what pain is supposed to make us do. Get away from the thing that causes us harm or death. Harm and death need to be unpleasant or will not avoid them and die.
Except that pain isn't necessarily the ONLY possible mechanism for preventing organisms from harm/death. There are plenty of designs created by evolution that are far less than ideal. Take the human eye, for instance. Our retinas are backwards, but you're stupid if you think that it's physically impossible for a retina to exist that isn't backwards.>Classic example of people with a rare condition where people do not feel pain: they are constantly accidentally harming themselves, and must be under constant supervision so that they do not die. They are complete cripples. This is what we're asking for when we dream of a painless existence
Except that with transhumanist technology, your body would likely be far less fragile than it currently is. You could potentially have your organic body parts replaced with bionic parts, made from nanoengineered materials that are virtually impossible to damage.
