Stealing the event's electricity to power their Natural Intelligence is going too far. To make it worse, the cable is an unmarked tripping hazard.This gives you an idea. Putting on your clumsiest human expression and pretending to be distracted by something in the middle distance, you approach the long cable powering the NI. You make a grand show of getting caught up in it as you trip and tumble, dragging the cable with you the entire time. A distant crash rewards your effort as you feel the cable loosen as it unplugs. The change in the camp is immediate. Without the Natural Intelligence causing their collective robot psychosis, the robots come back to their senses. They thank you for helping them and start making amends for their electricity theft. While most of them start cleaning up the mess in their camp, a couple of the more DJ-y ones offer to help with your party. As you all heads back to your camp, you think how lucky it is this sci-fi branch is not a thinly-veiled metaphor for anything going on in the real world right now.
