To prolong life just prolong life seems questionable, especially since only the rich or powerful could afford such a huge measure, while the seriously and terminally ill, the ones who need it the most, would not be able to get it. Which seems immoral: people becoming vitually imortal just to do so, or to help the people who need it moat, yet most likely can't afford it?
