But if you ask me what is a human being, I'd say that we are the species that seeks to go beyond our limitations and beyond our boundaries. We didn't stay on the ground. We didn't stay on the planet. We didn't stay within the limits of our biology. And I would point out that, if it were up to the Luddites, human life expectancy would still be 37, and we'd still be dying from bacterial infections.
