The claim: aging, death, disease, cognitive infirmity and indeed involuntary suffering of any kind are wrong. A transhumanist civilization of superlongevity, superintelligence and superhappiness can overcome these ancient evils. If we act wisely, then future life will be sublime. — David Pearce
David, thou art a gentleman and a scholar of the highest degree. Here and now that is. Your presence and engagement here is appreciated beyond the words received. I would much enjoy to share a few drinks with you at your preferred pub in your native England, what's left of it that is. That said, if you don't mind, what are your responses to the following criticisms of the words or rather common understandings and generally assumed beliefs behind:
Aging: Is this not proof of progress? Proof of the journey at the destination? A fine wine is aged, and is worth a considerable amount. Perhaps you refer to the physical and biological affects of aging being essentially decreased ability and fortitude. Well, in a race with no timer, why bother to move?
Death: I view death as a necessity in this world, not as you might think however but more of an escape hatch. For example, being trapped in a cave. In such a scenario one would rather starve to death then sit there for eternity. It's complicated, though without death what appreciation would there be for life really, would it not simply be just another prison?
Disease: I'm a firm believer in overpopulation, that things happen for a reason. If I were to be infirmed myself in a clinical setting perhaps I would be encouraged to rethink this, if not revealed as somewhat of a hypocrite. What doesn't kill you makes you stronger, and what one brings upon themselves (this is to exclude random cases of illness) one should learn or at least desire to pass on a lesson.
Cognitive infirmity: While I don't have an effectual or "actual" philosophical counterargument or "justification" for as it's a simple biological reality, I'll offer an anecdote. Well a sentence that one can be derived from. There's two water guns, the first ones which casually lose pressure as the tank depletes, and the newer ones (granted from a score ago) that maintain constant pressure (CPS "constant pressure system") until the tank is actually depleted. Which would you prefer?
Involuntary suffering: Welcome to Earth or life. Is it a blessing or curse? A reward or a sentence? Either way we're all going to be here for possibly a while, best do your time. There's no true escape, David. Other than to avoid true eternal bliss.

Onto your three supers:
Longevity: Again, I challenge you to be alone or perhaps even with friends (or more realistically mixed company who hold opposing views to yours as this is reality) for an extended period. Everything is fine, no one has to worry about anything, all needs are met, and it's just you and other people. How long could you take it? Until you do this, some may say, accurately I might add, you're just talking or blowing smoke. A non-religious person (ie. when you die, you're dead and cease to exist in any possible, real or imagined form or state of existence) one of course would cleave to this like a frightened lamb in the presence of a pack of wolves.. and this is the only reality that can be proven so is thus understandable, but what if we don't really know all there is to know? Can you not be wrong?
Intelligence: Simply put, they say ignorance is bliss. Perhaps they could be wrong. Perhaps you may be. Let me ask you, what were the best times of your life? I'll wager money that it was discovering new things, emotions, or moments. You know I'm right. What fun is a game you've already beat or a book you've already read compared to one you haven't?
Happiness: What is happiness? Why would one seek or even value peace if one could never pursue or make war? Love if one never knew hate or fun if one never knew boredom? Duality I believe some speak of. They may have it wrong or corrupted but perhaps they don't. What makes you happy David, if you don't mind sharing? What makes you sad? Why is that? If either were removed (incidents, experiences, or knowledge behind said emotions), would you feel the same toward the other?
Again, these are just criticisms meant to prod your response and beliefs on the matter, a response which I am eager to receive. "Just curious", as they say.
