Jails and prisons are one of the most burdensome expenses in the united states, costing billions of dollars per year. Wouldn't having automatic penitentiary systems with robot guards as a backup reduce the cost and also cut down on escapes? Most jail breaks happen from the inside due to corrupt officials either facilitating the escape through action (providing the prisoners with contraband) or inaction (not forcing them back in their cells or stopping revolts) so it makes sense that robotic wardens and an automated prisoner tracking system (like electronic collars) would be the best way to ensure fair and safe justice. Think of those mostly fully automated factory farms where the animals are shuttled around, fed, taken care of etc by machines. We could be doing that with our own prisons where animals (criminals) have exact routine schedules to follow. This way you dont have to pay for prison staff.

South Korea seems to already be trying to implement a form of this idea with their new high-speed robotic guards.
