in a thousand years someone unearthing a vinyl or shellac recording could put a sharp thorn through the end of a large leaf rolled up into a cone, spin the disc on a stick and hear Bobby Goldsboro's 'Honey'!

The main point being that what is on the recording determines it's value, the secondary point is that all the being of the future could do with a cd he stumbled upon is check his makeup in the reflection.

Simple technology is often the best long term, we haven't done much with the wheel since it's invention, after all, except minor improvements. All the new ipods etc. will be the eight track cassettes of thier day, soon obsolete and variously obessed about or forgotten by those who knew them. Digital technology will never equal the quality of analog forms, either sound or picture. They are just new.
