I have a UPS solely so that a power glitch does not interrupt the eternal building of HLODs for an 8K world. 11 hours and 42 minutes, so far. Without one, I know exactly what would happen next.
"Dear! DEER!"
"Holy cow!"
[Big swerve. Hits power pole. Deer is fine. People are fine. Car is not so fine. Power pole is all messed up. Transformer explodes. Power dies.]
Me: "AAAARRRRGGGGHHHH!!!!"
