Asteroid impacts or supervolcano eruptions come to mind. But since about the invention of the atomic bomb, humanity has been able to wipe itself out, adding self-made existential risks to the natural ones. Oxford philosopher Toby Ord argues in his book The Precipice that those risks are much more likely than the natural ones. In this episode we explore this idea with him, and also discuss what we should do about this realization.2020-08-222h 40podcast (en) Archive 250 EN – omega tau science & engineering podcast348 – ATLAS ComputingTo conclude our detailed look at the ATLAS experiment, this episode looks at the computing infrastructure.
