If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
OB was sponsored by the Future of Humanity Institute, (IIRC) so perhaps they encouraged RH and EY to post there? You could always ask at Robin Hanson's monthly open thread.
You've got a lot of backwards arrows in that diagram there.
