Sam is clearly one of the top product engineering leaders in the world -- few companies could ever match OpenAI's incredible product delivery over the last few years -- and he's also one of the most connected engineering leaders in the industry. He could likely have $500M-$10B+ lined up by next week to start up a new company and poach much of the talent from OpenAI.
What about OpenAI's long-term prospects? They rely heavily on money to train larger and larger models -- this is why Sam introduced the product focus in the first place. You can't get to AGI without billions and billions of dollars to burn on training and experiments. If the company goes all-in on alignment and safety concerns, they likely won't be able to compete long-term as other firms outcompete them on cash and hence on training. That could lead to the company getting fully acquired and absorbed, likely by Microsoft, or fading into a somewhat sleepy R&D team that doesn't lead the industry.
