We Should Give Extinction Risk an Acronym

Edit: At the suggestion of a commenter I am including some definitions for clarity.

Existential Risk (x-risk) [Bostrom’s definition]: An existential risk is one that threatens the premature extinction of Earth-originating intelligent life or the permanent and drastic destruction of its potential for desirable future development.

Extinction risk: Future events that threatens the premature extinction of Earth-originating intelligent life.

S-risks: Future events with the potential capacity to produce an astronomical amount of suffering.

I feel like people sometimes use x-risk when they mean extinction risk because they want to use an acronym. Plus it would be nice for extinction risk to have an acronym anyway (if it doesn’t already—I did a quick search and couldn’t find anything).

Some possible candidates:

  • e-risk (obvious choice but could be confusing since existential starts with e)

  • d-risk (death, or disappearance)

  • a-risk (annihilation)

Feel free to propose a different acronym, or why this is a bad idea.
