As a kid I got used to growing up with popular comparisons: “the height of Nelson’s column”, or “the size of 10 double-decker buses” or “as much as a whole tennis court” or “about the size of Wales”.

All of these stand the test of time (sort of – I mean, Nelson’s Column really isn’t that big).

But with the speed of innovation in the tech sector, somehow it just doesn’t impress me as much. So it’s cool that the NSA collects more than a Library of Congress worth of data per day but I have no idea what that means anymore. For all I know, my Home Server might store that amount... The latest 5 Bazillion MP camera probably has snaps of me with more data than that...
