In January 2024 I was invited by the Senate of Chile to speak at Congreso Futuro in Santiago. In this talk, I discuss Effective Altruism, a philosophy and social movement on which my early work has had a major influence and which has, in turn, influenced my thinking. The young philosophers who started it had read my 1972 article "Famine, Affluence and Morality," and rightly added an emphasis on using evidence and reason to find the most impactful ways to make the world a better place. Effective altruism challenges us to make doing that a central goal in our lives. In my presentation I stress the importance of considering all beings capable of suffering, including non-human animals, in our efforts to alleviate pain and promote well-being. I focus on extreme poverty, the ethical treatment of animals, and the implications of Artificial Intelligence on both humans and animals. For those interested in diving deeper into my views about global poverty and what we can do about it, I encourage you to download a free copy of my book "The Life You Can Save" from my website. (But be warned - one person I know described it as the most expensive book he had ever read!) FYI, this is a direct clip from the live stream of Congreso Futuro 2024.
