I feel like every time GitS-style full body prostethics are brought up as a happy alternative, people forget all the downsides they came with. Undiagnosed failures (the new movie), privacy invasion (SAC), interface allowing outside hacking (almost all episodes), interference with real memories (AA), etc.
Replacements operated directly and only via the nervous system, with no extra interface - sure. GitS-style body parts - no, thank you.
