> I agree with this analysis, and find it overall reasonable, but it seems to need a little more evidence, e.g. do we have any data that shows companies who put "generic managers" on top on regular fail more than those who put engineers on top.

That could be hard data to gather systematically. It's not like businesses fail immediately when you put a "generic manager" in change. A company can coast for decades before problems become obvious, and generic management confusing things even further by focusing on manipulating the most visible metrics (e.g. stock price) while taking actions that damage long term prospects.
