People are Amazing

Electronic eye Italiano: Occhio elettronico 

Humans attempt on a daily basis to recreate technology that already exists in our bodies. Cameras are a pretty primitive attempt at an electronic eye. Machinery we create will never be as efficient as human muscle or bone. Dialysis (while crucial to the current medical field) will never be as efficient as the human kidneys.

People are amazing, amazing things. The most powerful on-board computer interacting with the most sophisticated peripheral devices carried by the most ultimately all-terrain vehicle, and it's all regenerative and self-sustaining (Brain). How incredible is that?
