> any C-level exec will hold on to the position for dear life until they are forced out
I don't know. Frank Slootman's retirement from Snowflake earlier this year was certainly not celebrated by any significant stakeholders. I'd imagine at some point someone like Frank realizes that they are worth more than Tim Cook, they consider that they're in their mid-60s, and they decide the remaining time they have on earth might be better spent in other ways.
Every person in the workforce, no matter how ambitious or how senior, is forced into the calculus of money and power vs. good years remaining. I expect the rational ones will select the balance point for themselves.
