Agreed. People already live quite long, so immortality would take a very long time to make a difference with how things already are. If the first person to live 150 years is twenty years old today, he will reach that age in 130 years, that is in 2148. I believe that in 2148, the world will be vastly different than it currently is, and to a degree we can't even imagine. So to me the desire to be still alive then sounds naive, even futile. I understand that from a subjective point of view, and especially to people who fear death, immortality is of prime importance, but in the grand scheme of things, it's just a detail : paradoxically it does not matter in the long term because its effects take too long a time to manifest.
