Existential risks are threats to our future. Examples include nuclear war, some (possibly engineered) extremely lethal disease, and threats due to emerging technologies.

The effective altruism movement is a friendly alliance containing those who see existential risk as a top priority together with those favouring more conventional causes such as poverty alleviation and animal rights.

The question to think about for this meeting is: is it sane and altruistic to try to reduce existential risk?

Sub-problems:

• how morally relevant are the vast number of potential future generations?

• which existential risks do we focus on?

• how do we make existential risk reduction tractable?

• in particular, how do we measure the risk of something that hasn't happened yet? How do we know we're reducing it?

• overall, how does xrisk weigh against other areas of EA interest?
