Going, Going, Gone: Vanishing Americana, one of my favorite books, offers compelling evidence of how fast our world is being transformed. On page after page, we see products, services, vocations and styles that once seemed integral to daily life but have nearly or completely disappeared. Remember milkmen? Carbon paper? Phone booths? Drive-in movies? Vinyl records? All gone or mostly gone. OK, that last item is making a bit of a comeback, but downloading music has become so pervasive that in many homes even CDs are already obsolete.
Much farther down in the scrap heap of history is the IBM Selectric typewriter I relied on in the 1970s. Back then, its use of a ball-shaped typing element instead of keys rendered it cutting-edge technology, but it would look like a fat relic next to one of today’s laptop computers. As for the “Magic Brain” mechanical calculator I carried around in junior high, thinking about it now just makes me laugh. I’ve actually seen ones just like it in antique stores.
