PhD Holders vs Projector

How many PhD holders are needed to set up the projector?
One of our colleagues needed to set up his notebook to link to the projector for our meeting. However, the technician wasn't around so we were on our own. It started with one, then two, then three and in the end there were 3 PhD holders, 1 PhD candidate, and 1 manager who were mulling around the controls and trying to work out how to fix up the projector. Unfortunately after 15 minutes, still nothing. In the end, it was another manager, the 6th person, who managed to set it up lol. 
In the end , none of the PhD holders were able to fix up the projector. LOL. What my mother said on an occasion suddenly makes sense - the more educated you are, the more stupid you become. Perhaps we stop being an all-rounder once we started specialising in our area of knowledge. Perhaps we stop learning about other areas unrelated to our area of expertise. Perhaps we also become more adverse to taking risk... Perhaps we should start learning again about everything else around us.
