There was something odd about Unit 004. Sure, it was old — it was one of the earliest Synthetic Intelligence Robotic Assistants ever produced — but age didn’t explain its quirks. Neither did its programming; on the surface level, its software didn’t display anything abnormal for a model of its age. In fact, it was very normal: it had somehow avoided all of the common mutations and defects that evolved in early SI models. Yet there was something very eerie with its occasional memory glitches. Sometimes upon reboot after a long recharge cycle, the unit expressed clear disorientation with regards to its identity and purpose, sometimes becoming wary and nervous. After its actions escalated to hostility towards humans, the unit was decommissioned and recycled for parts.
