Astral Codex Ten published Open Thread 454 as a weekly space for reader discussion, alongside several community updates. The post notes a BYU meetup change, newly translated Fatima documents, archived book reviews, a physicians’ AI safety group, and the author’s limited recent writing time.
The post describes the thread as the site’s weekly visible open thread, where readers can post about anything or ask casual questions. It points readers to an unofficial subreddit, Discord server, bulletin board and in-person meetups. The site’s content is partly free and partly subscriber-only, according to the post.
Among the notices, the post says Brigham Young University’s Effective Altruism college meetup has changed its time, date and location, and directs readers to check the meetup list for the revised details. It also credits reader Nikita Sokolsky with obtaining additional Fatima-related documents from Portugal and translating them into English, with help from Ana on work requiring Portuguese proficiency. The documents are available at fatima-1917.com, the post says.
Rob Ennals, who created the current year’s book review contest site, has collected reviews from earlier years into EPUB files, according to the announcement. The post also gives Physicians For AI Safety a chance to publicize its existence: the group says it wants to speak with physicians interested in AI safety and has an open letter for them to sign.
Updates for ACX Readers
The post’s significance is mainly practical for readers already connected to Astral Codex Ten. The BYU meetup change could affect people planning to attend, while the newly gathered Fatima documents and archived reviews make materials easier to find in English or in ebook form.
The announcement also offers a point of contact for physicians interested in AI safety. It does not describe the group’s positions or activities in detail, so readers should treat the open thread as an introduction and consult the group’s letter for its stated aims.

A Weekly Community Forum
Open Thread 454 follows the format described by Astral Codex Ten: an open-ended weekly discussion alongside brief notices for its readership. The post directs readers to several community spaces and meetup listings rather than presenting a single reported event or investigation.
The notices span separate projects. The Fatima documents were gathered and translated by readers, the earlier contest reviews were compiled by Rob Ennals, and Physicians For AI Safety is using the post to reach potential physician contacts. The source does not give additional details about the documents, the review archive, or the organization.
“This is the weekly visible open thread. Post about anything you want, ask random questions, whatever.”

Details the Post Leaves Open
The post does not state the revised time, date or place for the BYU meetup; readers are referred to the separate meetup list. It also does not summarize the contents or provenance of each newly translated Fatima document, or specify which past book review contests are represented in the EPUB collection.
No details are provided about Physicians For AI Safety’s membership, policy proposals or the text of its open letter. The post gives no date for when Scott Alexander expects his workload to ease, so the timing of additional writing remains uncertain.
Check Listings and Project Pages
Readers interested in the meetup can consult the linked list for the updated BYU details. Those seeking the translated documents or review EPUBs can visit the respective project pages, while physicians interested in the group can read and consider signing its open letter.
The thread remains open for reader discussion. Scott Alexander says he will try to make up for the recent lack of writing after his schedule changes, but gives no expected date for that return.
