"1010001" in decimal is 81, which is also the atomic number of thallium, the metal that the crew seeks out in the west.
When panning Amy says they can't find any thallium, just worthless gold. Gold is actually also used in semiconductors and microprocessors, while it is not as electrically conductive as copper and silver, it is more conductive than thallium. The reason gold is used over copper and silver is that it is far less reactive, meaning it doesn't corrode the way copper and silver do, plus it is very good thermal conductor. Which is also why thallium is used in semiconductors, it is a poor electrical conductor, but an excellent thermal conductor, so thallium is used to help microchips get rid of heat more efficiently.
The guitar Bender plays is the 3D printed copy of folk singer Silicon Red's guitar he made in Forty Percent Leadbelly (2013) while trying to become an even bigger folk singer than Red.
