Ironman at Political Calculations (host of the most recent Cavalcade of Risk), has a thought-provoking - and inspiring - post on tech obsolescence:
"Think of things like buggy whips, or Commodore 64 computers, or newspapers, or DVDs."
These have all gone away (buggy whips) or evolved into something new (DVD's). But Ironman points to one example that "would be instantly recognizable to a time traveler from the past for what it is."
Can you guess what that is?
The answer may surprise you, as may the tech that just might supplant it.
