[Futurama] Why Bender can't get a Backup Unit installed ?

In a lesser extent, was it really impossible to upgrade his son to allow to bend without erase his memory ? At worst if they had to replace the component with his personnality, they still could copy it in a better one. (Since robots use 24 hours backup they don't have a problem with continuity of consciouness)

And why humans don't use a Backup Unit implant / Cortical Stack themselves ? they could become immortals (Without living in the Near-Death Star's simulation) or at least avoid premature death.

What you're suggesting is the Futurama robot version of "Download more RAM."

Its just ridiculous. Now what you want to be spending your time on is some kind of atomic supermen with octagonal shaped bodies that suck blood.... 

To be a bit more specific, the very act of changing how a robot works by adding something integral that wasn't there when it was created (or born even, depending on how you look at it) changes the very fundemental base that makes that robot who they are.

You saw what happened when MoMCorp brought that new floaty robot out and all the old models had to go for "upgrades". There are two things you can do to a robot without changing their personality. Cosmetic upgrades (Extendo arms, X-ray vision, neon crotch) or a kind of electro therapy minor reprograming.

Anything more than that pretty much gives it a new personality, so Bender would cease being Bender. He'd have the same body, but he'd be a different bot altogether.
