I think of technically competent as having been a hands on dev, Zuck at least did that during his time (like Gates in his day). Satya and Sundar were not hands on in terms of coding and were PMs in their respective companies before moving up the ladder. This makes sense for the CEO role, but if the question is technically competent CEOs, not sure they'd be representative, of course they have computer science backgrounds/education so it's debatable.
