There's an ongoing discussion on Reddit which has reeled in a lot of comments.
Take a look. It is essentially the age-old conflict between those who want to cure aging and those who think aging is good, our lifespans are enough, we must all die to make room for our children, etc.
What really surprised me is how many are in that second category. Not something I'd expect from Reddit. Kind of tantamount to seeing a huge evolution vs. creationism thread, isn't it?
