Monolog in a dungeon

This was at the Distributed Web Summit
held by the Internet Archive
at the San Francisco Mint,
where they used to make silver coins.
Left alone in a bricked-up cell,
by Gary (Zhexi) Zhang of MIT,
this is what I said.
With long pauses for passing caravans.
Gary intends it to be part of a longer work;
good luck to him.
