While the market is what promotes the new technology, it's also what saves the old.
Who would create art if there were no demand? I mean, you can't steal from folks until the end of eternity to
produce that which nobody wants, so in the end, there must be a demand, if only from hobbyists and the like.

A surprising amount of old tech survives in the hobbyist realm, though, and if times got so tough that humanity
lost some of its technological foothold, I'm pretty sure there are folks who could step up and ease some of that old
tech up into the foreground again.
