The only problem with that (if you care about what happens to humanity after you die) is that it will likely result in a major collapse of society. The religious nuts and those in regions of high child mortality (which means they're all poor and uneducated) aren't going to be able to maintain or advance a technological society. They can breed, but that's not enough to know how to keep complex systems running, and things will collapse just like Ancient Rome, with technology being lost and everyone going back to being feudal serfs, or worse. Personally, I just don't see a way to avoid some kind of major collapse of society due to one or more of the many factors facing us. For this issue, I think greatly improving human longevity is absolutely necessary, and if we don't do that, we're going to have another Dark Ages of some kind.
