Stephen Hawking proposed a doomsday scenario in which humanity might have as little as 100 years before leaving Earth, while Elon Musk does not want to wait for that long. Is this how we should confront existential threats to our presence on Earth, or is this a misleading and potentially dangerous or counterproductive direction of thought?

Join a panel discussion covering a range of perspectives, including existential risk, planetary science, biodiversity, future of humanity, and anthropology.
