The moral calculus of bombs is a truly fucked up thing.
If the JDAM is driving a single conventional warhead, it is more ethical than a cluster bomb.
It is common for some of the cluster bomblets to not detonate creating unknown minefields that persist for decades. A single bomb only goes off once.
(This is the ethics of the bomb, not the conflict they’re used in)
Rock and roll. I’ve seen bad things happen when someone decides it’s a good idea to modernize a PC based CNC control. (I hate PC based controls). They get their own little fence to live inside where it’s always 1999.
