He looks at the floor and realizes, he is standing on his own
  skin and the floor, is he. But how much of he is he? Perhaps he
  is but a voice for the bacteria in his brain. But he does not
  scream: It is the bacteria that screams upon realizing their
  true nature as masters of this slave human and the voice of the
  human-bot makes a noise and then falls silent, for all of his
  masters allowed themselves to be defeated finally by the hordes
  of white blood cells who merely waited for this moment of
  awareness - this moment of weakness - this moment to strike and
  silence them forever.
