I cover this topic extensively in the book. I think the fact that founders are increasingly turning to the political solution of "despotic emperor for life" tells you more about how bad standard governance is than anything else. I think vesting this power in a singular person or small group of people has all the downsides you'd expect from studying history. In the psychology literature, they literally have a name for "hubris syndrome." That is a mental illness that sets in when people have too much power.
In the book, I make the case for what I call constitutional governance, which I see as a third way in between standard governance and founder-controlled governance. I think it is both more effective and more long-term. After all, a company that is tied to the human lifespan has a built-in expiration date.
