Not investors: venture capital investors in tech. It's a particular kind of investment in a particular industry. Tech VC's are in the business of selling business futures, not building mature businesses. The buyer they sell to can install a practical CEO and worry about actual operations when that time comes. In the meantime, enthusiastic kids provide a relatively cheap, manipulable, supply of powerpoints and pizazz -- whereas sober, mature professionals often need more personal income and tend to focus more on executing the business that they have experience in (mostly irrelevant to the VC's own business) instead of matching the investment pitch for upcoming rounds (all that matters).
