Happy Easter and Passover! This is the bi-weekly visible open thread (there are also hidden open threads twice a week you can reach through the Open Thread tab on the top of the page). Post about anything you want, but please try to avoid hot-button political and social topics. You can also talk at the SSC subreddit or the SSC Discord server – and also check out the SSC Podcast. Also:

1. Matt Arnold is resuming his work on an Unsong audiobook. Existing chapters here, Patreon to support him here.

2. An NYC rationalist group is holding a special spring Slate Star Codex meetup Saturday, May 4th, 3-7 PM, at 180 Maiden Lane in Manhattan. All readers in and around NYC are invited. There will also apparently be some sort of optional networking thing; see here for details.
