Tablets didn't die. We still inscribe words onto metal and stone. And, yes, I'm including tombstones and other memorials as being tablets.

I can't think of anyone who still makes scrolls, or papyrus, or vellum, or writings on birch bark, but I'm sure someone does it, if only as art.

Some technologies do die, like Williams-Kilburn tubes and mercury delay line memories, but others are relegated to roles where they still shine.
