There’s a saying (which I’m sure has an English equivalent) where I live that goes something like “It’s the owner’s gaze which fattens the cow”.
Owner vs manager is the original “AI alignment problem”, usually taught as the principal-agent problem in business schools, and is very real. SV-type founders are, by and large, meaningful owners in their enterprises and thus heavily invested (literally) in the company’s performance. Professional managers, leaders or not, are just selling their labor. There is a whole field of management science about designing proper compensation structures to make CEOs better aligned with shareholders, but you get that quicker by making them the same person.
Of course there’s a whole other world of majority shareholders leveraging their position to extract value from minority shareholders, which is just another version of the same problem.
All this to say, you’re right that there’s prior art about what he’s writing, but its the principal-agent problem, not leaders vs managers, and in general business literature does not equate the issue of founder ownership with the PA-problem (obviously any undergrad can link the two issues, but that’s not how they’re usually approached)
