Death is a moral responsibility. You owe your existence to evolution. Evolution would not work if we had to compete for resources with all of the organisms that came before us when they didn't die off. Death is an integral part of living a bringing our species forward. Your responsibility is to make the best of your time here. Have fun, love, and contribute to society and science if you can. Then die and make room for the next generations.
A moral responsibility under which moral framework ?
Why do I owe anything to my genes or the process that created me nearly by accident ?
Why do I not have a moral responsibility to find a better path than random evolution ?
Evolution isn't a person, or an entity to be compensated. It's a natural process. If humans can surpass it, find a new way to improve themselves, then do it. All of this argument seems like one extended appeal to nature, combined with some backwards-justified reasoning as to why being limited in time is a good thing - start with the premise that our lives are short, and then find a way to make that sound appealing.
I don’t think you get to ‘surpass’ evolution with regards to increasing life span. Maybe you can retard the process. But I think that is just kicking the can down the road.
Its like an old growth forest not being allowed to burn, it’s caretakers keeping it in media res for as long as possible until it eventually burns anyway and the natural cycle continues.
Evolution doesn't have a "forward". If we were unable to outcompete our ancestors, then we simply wouldn't be better adapted to our environment than they.
