But we are also currently attempting to be multi-planetary, and though Earth's resources may be finite, perhaps the solution to living forever is using less resources (doubtful, but can't we cross that road when we get to it)? We shouldn't try to create an electric self-driving car because it might kill somebody, but people are being killed by non-self-driving cars, so are we really any worse off? If the limit of Earth's resources means that we will run out and some of us who would live longer will die earlier than we'd hope...well, we're already doing that.
