The time this takes place in is April 2097 a year after recall where spring showers hit the most and plants grow rapidly.
This is set in a future setting but it’s widespread futuristic. Example Are there droid like robots? Yes but only large commercial franchises would be using them, It was a plan for domestic droid robots to be in houses by 2100 with the Dunkum batteries tech.
Second this is a Simple town even before the recall. So while they do have access to modern tech, which has to be powered by dunkum now. It’s not holograms and laser weapons. Voice recognition and a robotic (Not cybernetic) prosthetic would be the most advanced tech behind the Dunkum.
