Why would he? As previously established, they like their continuity. It wasn't long ago that they established that when a robot "dies" their memories are downloaded into a new, duplicate body. Bender doesn't have that ability, but other robots do. Why wouldn't Calculon just download into a new body and continue acting like usual?
Yeah...that "back up" unit reveal raised some continuity questions.
Odd that earlier Bender thought he was a disabled robot and toured with Beck...bringing attention to disabled robots everywhere.
Why wouldn't the robots just "die" and download into new fully functioning bodies?
What about the robots that are "born" not manufactured? How can they be downloaded into a duplicate body?
