Let's say someone with advanced manufacturing capabilities decided to make silicon based life using a human as a template.
Description of the silicon being
- Only the exterior of the being is human shaped (assume average human)
- Pale white skin
- Completely black scleras and retinas
- Black hair
- Can talk and do just about anything physically a human can do
Is such a being possible? What would be the differences in the biology of the being compared to a human? Is there anywhere this being could/couldn't go that a human could?
