About being ignorant

Upon reading a book on a flight back to Riyadh recently, I stopped to ponder the following quote from a Neil Postman book Technopoly.

Based on old adage (some attributed this to Mark Twain)

To a man with a hammer, everything looks like a nail

And Neil Postman in his book extended it to :-

To a man with a pencil, everything looks like a list .
To a man with a camera everything looks like an image.
To a man with a computer everything looks like data and to a man with a grade sheet, everything looks like a number.

A good friend of mine used to say .. to his manager he was just a name in Excel sheet!
