The website for Manifest 2023 (Manifold's planned September conference in Berkeley) lists Scott Alexander, Aella, Destiny, and Robert Miles ("...and more") under "Speakers & Guests of Honor." [UPDATE: It no longer lists Scott.] Will each of them show up and be part of the official program in some way?

[CLARIFICATION: To be part of the official program, a person must somehow be leading an event - broadly defined. For instance, giving a talk, running a session, or being on a panel. Even if a person is a Guest of Honor, they must be part of the official program to count for this market. See my other market for one without this criterion.]

For this market, a virtual appearance counts as long as it's live (not pre-recorded).

I hope to attend the conference to verify, but otherwise I'll get info from people who were there.

General policy for my markets: In the rare event of a conflict between my resolution criteria and the agreed-upon common-sense spirit of the market, I may resolve it according to the market's spirit or N/A, probably after discussion.
