Investors have little time for appointing mavericks and even if a former owner and developer of a company comes back he often faces incredible resistance from present investors. Michael Dell and Steve Jobs both experienced that. These guys think long term typically way beyond what investors are looking at.
So the irony is that many investors shoot themselves in the foot by refusing to allow the very people to be put in charge that would increase the long term value of the company.
The thing about passionate mavericks - they invent the future and the market follows them (they need not be geniuses they just need to implement an idea competently with passion and before everyone else - it’s a lot different from being a genius.
