For Existential Choices Debate Week, we’re trying out a new type of event: the Existential Choices Symposium. It'll be a written discussion between invited guests and any Forum user who'd like to join in. 

How it works:

• Any forum user can write a top-level comment that asks a question or introduces a consideration, the answer of which might affect people’s answer to the debate statement^[1]. For example: “Are there any interventions aimed at increasing the value of the future that are as widely morally supported as extinction-risk reduction?” You can start writing these comments now.
• The symposium’s signed-up participants, Will MacAskill, Tyler John, Michael St Jules, Andreas Mogensen and Greg Colbourn, will respond to questions, and discuss them with each other and other forum users, in the comments.
• To be 100% clear - you, the reader, are very welcome to join in any conversation on this post. You don't have to be a listed participant to take part. 

This is an experiment. We’ll see how it goes and maybe run something similar next time. Feedback is welcome (message me with feedback here).

The symposium participants will be online between 3 - 5 pm GMT on Monday the 17th.
