depends how you define the invention in question or even "dead". with voip and mobile phones are we taking about the same invention? because talking-to-other-people will likely never die. are you calling that the "telephone". vinyl LP's are not "dead" as in non-existent, 0% adoption, etc, but they are a lot less prevalent than they used to be. cd's too. what if electronic ink supersedes regular ink in newspapers? is it still "print". inventions evolve they don't die.
