By the way, check this out. Thought it might be interesting to perhaps integrate some of that into how the machines work.
I imagine there are also pets are a hybrid or artificial and real biology, like the 'CPU for brain humans' anime you referenced. Perhaps the dog is a 'dog' but with a bio-photonic brain? The body can age and die, yet the crystal cortex can be recovered (or runs to gloop like a self-terminating Artiloid).
Why am I thinking 'pet reincarnation' here?
