Scrubjay thought about how Spider City had grown organically around the new homes that people dug inside lava tunnels. Every resident was part of the chore rotations that allocated agricultural work, which kept the city’s farms robust. They planted enough to feed all the biologicals, while the geothermal energy grid fed the bots and fleets when they weren’t using solar. The train had never thought about food and housing as things that could be scarce, like beta access codes for a game.
