Is that actually true? I've met very few project managers who know any discipline other than project management with anything I would call depth. I can't even imagine talking to a PM about any serious technical question anymore. Their answers in the past have always been a unique type of unhelpfully vague but hard to argue with which puts all the effort back on you, but not in a way which adds anything to solving the problem. Things like "what's best practice" when I've just exhaustively explained how we're in the precise corner case to which the normal best practice doesn't apply are, for me, the hallmark of PM ideas. Deep technical insight or domain knowledge are not.
