Longtermism is a philosophical perspective that emphasizes the importance of considering the long-term future when making decisions today. It argues that actions taken now can significantly impact future generations, and therefore, we should prioritize the well-being of those who will live in the distant future. This approach often involves addressing global challenges like climate change, technological risks, and existential threats. Proponents of longtermism believe that we have a moral responsibility to ensure a positive future for humanity. They advocate for policies and practices that promote sustainability and resilience, aiming to create a world where future individuals can thrive. This perspective is often associated with organizations like Effective Altruism and thinkers such as Nick Bostrom.
