“She [Helen Toner] Did Not Expect to Be Busy on Thursday”, Oliver Habryka2023-11-19 (OA)⁠:

…this [Sam Altman firing on 2023-11-17] is unlikely to have been planned long in-advance. For example, for unrelated reasons I was planning to have a call with Helen last week, and she proposed a meeting time of last Thursday [2023-11-16] (when I responded with my availability for Thursday early in the week, she did not respond). She did then not actually schedule the final meeting time and didn’t respond to my last email, but this makes me think that at least early in the week, she did not expect to be busy on Thursday.

There are also some other people who I feel like I would expect to know about this if it had been planned who have been expressing their confusion and bafflement at what is going on on Twitter and various Slacks I am in.
