He rubs elbows with very powerful people including CEOs, heads of state and sheiks. They probably want 'one of them' in charge of the company that has the best chances of getting close to AGI. So it's not his technical chops and not even 'vision' in the Jobs sense that keeps him there.
Are they really the ones with the best chance now though?
They're basically owned by Microsoft, they're bleeding tech/ethnical talent and credibility, and most importantly Microsoft Research itself is no slouch (especially post-Deepmind poaching) - things like Phi are breaking ground on planets that openai hasn't even touched.
At this point I'm thinking they're destined to become nothing but a premium marketing brand for Microsoft's technology.
