(Your point is good, but the dig against MBAs is unnecessary and I wish it was less acceptable here on HN. It wouldn't be ok to make fun of people with Sociology degrees or History degrees here, but jokes about MBAs get a pass. We really should be better than that, but I realize I'm swimming against the current on this one.)
That aside, I have found a lot of clueless folks in tech leadership have that "furiously typing" misconception, as if developers are only productive when their fingertips are pounding keys. I once worked with a CEO who refused to set aside time in the schedule for things like setting up source control and a bug tracker, because he believed that developers should be furiously typing code in at all times.
