That may just be the way the article is written, but I find all these people to be a bit too much self-centered and maybe too much on their bodies, in my opinion. There is more to old age than just the body. I personally think that if everyone could live forever (in flesh or not, maybe just in a sort of library/archive), the biggest advantage would be that experiences are retained. It is just a shame to think about the amount of knowledge that is lost every time someone dies. And the effort needed to train the next generation. On one hand, that means we get to imagine better ways of teaching, on the other hand, we have to spend more time studying, or just accept that we won't know everything perfectly (and be more specialized than our ancestors were). This specialization is only compatible with technological improvement if we can delegate more of the low-level task/knowledge to computers/AI, or if population keeps increasing (which isn't really sustainable, long-term). The alternative is stagnation, or regression in some fields to progress in others. Edit: I can get some people not agreeing to this view, but this was meant at the starting point of a discussion, not a general truth. Could the downvoters at least share their view of the topic?
