A robot’s anatomy
Ultimately, doctors need to know all about anatomy. If a surgeon cuts you in half, they need to know where your guts are so they can put you back together correctly. That is why they need x-rays and other procedures that will show them your insides.
For a couple of years now scientists have talked about how in the near future artificially intelligent robots will be living among us. As far as we know, even though they may look like people, their guts would look like the inside of this engine.
