Thing is, while PhDs are usually by far the biggest domain experts you'll get, the absolute majority of them comes absolutely ill-equipped to lead anything, as university rarely teaches any skills in project, people or resource management skills, business sense, opportunity cost and presentation.
I've had disastrous outcomes going by credentials for leadership positions and these days only hire for demonstrated results on a real-world project.
Just my personal anecdotal evidence points me towards stellar academic success having a slight negative correlation with on-the-job performance. People who prefer building things with impact over citation rubber points usually don't survive in academia long enough for enduring a PhD.
