Machine Intelligence Research Institute (MIRI) — Headcount: 18

NoteThe source URL (https://intelligence.org/2024/04/02/2023-review/) is supposed to contain MIRI's 2023 review, which would be the appropriate source for verifying headcount as of 2023-12. However, the source text provided is a 404 error page ('Page Not Found'), which means the actual content is not accessible. Without access to the actual review document, the claim about 18 employees cannot be verified against the source. This is an access/availability issue, not a contradiction — the source exists in principle but is not retrievable in this context.
