Again, I'm thinking in terms of vacuum tubes, and
I can't see how losing
the knowledge of how they worked is going to affect the future, or even
the present for that matter.
I'm guessing that there is at least one piece of equipment in your house
that relies on a vacuum tube to opperate that is not some sort of display
device.
We're so beyond them technologically that they are
irrelevant today.
So you don't want television, or radio, or communications satellites, or
radar, or ...
