Late only because of how swiftly Sam and Greg had agreed to work for Microsoft. This is sent on the first day back to work after the firing assuming OpenAI doesn't work full staff over the weekend. Furthermore contacting 700 people and getting a response back takes a little time too.

Let's be honest, Microsoft will probably be happy for Sam and Greg to return since OpenAI is almost a Microsoft company and it causes the least disruption. Alternatively could OpenAI go to 💩 and Microsoft lose their Edge (😉) over competitors in this space.
