Managers should be technical enough to understand what is going on, but claiming that an effective manager needs to be coding 80% of their time (as the article says) is idiotic. Why be a manager at all at that point?
I've personally had much worse experiences with managers who wanted to micromanage every technical decision and every line of code vs. those who just trusted their team with it and focused on people management, clearing organizational blockers, roadmapping, project management, communication to executives and other stakeholders, shielding us from company politics and lots more.
