@cephalopie That's what it made me think about. What will be totally useless...or priceless tomorrow because the we deemed it. Seems almost too simple to make something valuable.
@kjo That was interesting. I don't wear a diamond ring, because most diamonds are blood diamonds. I found the rock interesting. I wonder what we value highly now, that future generations will consider odd, and useless.
