I think you're forgetting this:

"often turns out to mean is: hire professional fakers and let them drive the company into the ground."

That's not low risk, that's higher risk. Letting the founders continue in Founder Mode can be both lower risk, and higher expected value, at the same time.

> hiring good people and letting them do etc is all just details of dynamics emanating from this unreasonable risk taking ability

I think not. Instead, the founders have unique insights: in the product, in the business domain, in the people in the company - which lets them do Founder Mode things a professional CEO cannot.

Sth else:

> only really unreasonable people can make huge changes in society.

Nice way of phrasing it :-)
