One ripper says the electronic device are of course prone to EMPs and a giant solar flare.
I think the ripper across the road from where you get ping (could be wrong) says basically this (paraphrasing) yes you have sword arms, but when you replace the organic arm, the mechanical one doesn’t have as good wiring. The effect may not be noticeable with single “upgrades” but definitely can feel the difference over time
