Of course not all engineers are cut out for management and some don't even want to do the transition, but a lot of successful CEOs (especially in tech) come from a combination of technical background + MBA.
I would add that attention to detail (a characteristic from technical people) is a good indicator of how this transfer can be achieved successfully.
A healthy distrust of generalists is understandable, given that a characteristic of bsing is to talk in generalities (no details) and some are very adept at convincing interviewers of their supposed skills.
