Not just the Rank and File, but he was really was the face of AI in general. My wife, who is not in the tech field at all, knows who Sam Altman is and has seen interviews of him on YouTube (Which I was playing and she found interesting).
I have not heavily followed the Altman Dismissal Drama but this strikes me as a Board Power Play gone wrong. Some group wanted control, thought Altman was not reporting to them enough and took it as an opportunity to dismiss him and take over. However, somewhere in their calculation, they did not figure out Sam is the face of modern AI.
My prediction is that he will be back and everything will go back to what it was before. The board can't be dismissed and neither can Sam Altman. Status quo is the goal at this point.
