But he just got the job and I'm sure many people are on PTO/leave for holidays. Give the guy some time. (And this is coming from someone who is pretty bearish on OpenAI going forward, just think it's fair to Shear)
What could the reason be that would justify this kind of wait?
I'll point out that Sam also doesn't seem to want to say the reason (possibly he's legally forbidden?). And all of the people following him out of OpenAI don't know, and are simply trusting him enough to be willing to leave without knowing.
If you are a customer, arrange to use alternative services. (It's always a good idea to not count one flaky vendor with a habit of outages and firing CEOs.)
If you are just eating popcorn, me too, pass the bowl.
