The quest for immortality isn't a 0 or 1 objective. Using technology to reduce or reverse aging is one aspect. Using technology to reduce the accident fatality rate is another aspect. E.g, what was the car fatality rate 100 years ago and what is it now when you account for safer cars and better medical tech.

Unless you bypass the Second Law of Thermodynamics (Greg Egan's Permutation City provides a possible example), technology will get us asymptotically closer to true immortality. But even if we don't reach true immortality, reducing suffering caused by our current level of mortality is a noble goal.
