"Whether they care or not is irrelevant."
"Whether they care" may seem irrelevant to many people, but not me. The degree to which "care" is taken to prevent life-and-death errors truly matters. The amount of attention given and the measures taken to prevent and or manage error depends a lot on the "care" one takes. Granted, for robots, such "care" must be taken in the software development, but it is also taken when deciding how much authority is given to unthinking, uncaring automated tools, whether for control of an aircraft, control of weapons or most particularly control of targeting, and launching/dropping/firing lethal weapons.
I don't accept a General apologizing for a death due to "computer error".
