I have some concerns about a dystopian kind of future where people lose their consciousness in cyborg bodies, but I'm definitely for the idea of aging more gracefully into one's last years. I think we should aim towards a state where people can feel less back and shoulder pain and where they have more energy to do the things we love. That said, we can't stop our telomeres from shortening or our body being exposed to oxidants, so the march towards death will continue towards its inevitability.
I dunno. If feel like if it comes down to choosing a purely fleshy version of myself, or choosing a version of my self with cool cybernetic augmentations, I'm going to choose the one with cool cybernetic augmentations.
