I think the blog post goes to show that much like words change their meaning over time, icons can also come to represent objects that are much different from their original metaphors. As new generations of people learn to associate concepts with the icons that embody them, the original metaphor loses its importance. To give an example, the word "microphone" has only been used to represent modern microphones since 1929. The term referred to the mouthpiece for a telephone between 1929 and ~1878, and from ~1878 until 1683, it described ear trumpets.[1] [1] http://www.etymonline.com/index.php?allowed_in_frame=0&search=microphone&searchmode=none http://www.etymonline.com/index.php?allowed_in_frame=0&s...
