To compare the computer
with a brain is a fair analogy, as this is essentially the function of the brain.
To control human life, control his action and save his information in human
memory. The computer also store the data in the hard disk and it available in
any time the user ask about it.
If I compare a healthy
person to a broken down horse in a race just to make the person seem less
desirable or less honorable, that is a false analogy. You see it in the
politics section here all the time.
