To be honest, immortality sounds terrible to me. outright horrible. nothing to live towards, no goals you have to achieve within a certain time (so how would economics survive, or anything for that matter?), every disaster you'll survive, no matter what that does to you emotionally or physically, staying together & making a commitment with someone for the rest of your life becomes utterly useless, the difference between generations becomes either vague or disappears, & last but not least; if we 'win' immortality, that doesn't mean the rest in this world suddenly stops being ever-ending. there's no use to bond to a place, to care for anything, to love at all for that matter, as everything goes, besides you. even the hormones, that cause love. your life, your precious never-ending life, would be a chain of goodbyes.
An entire society of immortals may be a problem. For example, who wants to be a firefighter when one false step means you've blown the next billion years? No one would want to risk things, and the value of time would depreciate. People will take for granted all the time they have and forget that they were once a mortal race. "Why do it now when you could do it in the next billion or so years?"
I find it interesting what people say about the lack of purpose in life if there is no immortality. However, there are many different visions of immortality. There is the religious one (Heaven/Hell), the scientific one, (Live forever), but what about changing the world? IMHO, leaving your mark on the world is the only way to achieve immortality, at least for now.
I know eternity sounds wonderful in most ears, but.. I've seen my grandmother slowly dying without any reason to live in her life left. everything she loved had already gone away. it made so much sense for her to go away too. & she lives on. in my memory & that of her other grandchildren & her sons. on top her & her husband's life was described in books, practically she'll live on forever.
& if I'd die tomorrow, my life still would've made perfect sense. I've had wonderful moments, that not only I remember. I lived through numerous of things in which I felt & knew the support & love of others. What on earth happened to right now? we're only living in a future, that's ahead of us & might never come...
