Actual estimate: 0.05%

This was a direct response to Ord's estimate. It focuses on one pathway to x-risk from AI, not all pathways (e.g., not AI misuse or risks from competition between powerful AIs). "These estimates should not be taken very seriously. I do not believe we have enough information to make sensible quantitative estimates about these eventualities. Nevertheless, I present my estimates largely in order to illustrate the extent of my disagreement with Ord’s estimates, and to illustrate the key considerations I examine in order to arrive at an estimate." In comments on the source, Rohin Shah critiques some of the inputs to this estimate, and provides his own, substantially higher estimates.
