“Scope neglect is the hazard of being a biological human, running on an analog brain; the brain cannot multiply by six billion. And the stakes of existential risk extend beyond even the six billion humans alive today, to all the stars in all the galaxies that humanity and humanity’s descendants may some day touch. All that vast potential hinges on our survival here, now, in the days when the realm of humankind is a single planet orbiting a single star. I can’t feel our future. All I can do is try to defend it.”

— Eliezer Yudkowsky, Cognitive Biases Potentially Affecting Judgement of Global Risks (2008)
