"Hitchhiker's Guide to the Galaxy" is also predicated on the premise that the earth was an elaborate computer that was being used to compute a more meaningful answer than "42," to the Q, "What's the meaning of life, the universe and all that".

Finally, a subject I know something about! The Earth was not built to compute a more meaningful answer than "42," it was built to determine the question to which the answer was 42. Here are some relevant excerpts:
"Alright," said Deep Thought. "The Answer to the Great Question

"Of Life, the Universe and Everything ..." said Deep Thought.

"Is ..." said Deep Thought, and paused.
"42."

"I checked it very thoroughly," said the computer, "and that
quite definitely is the answer. I think the problem, to be quite
honest with you, is that you've never actually known what the
question is."

"But it was the Great Question! The Ultimate Question of Life,
the Universe and Everything!" howled Loonquawl.

"Yes," said Deep Thought with the air of one who suffers fools
gladly, "but what actually is it?"
"I speak of none other than the computer that is to come after
me," intoned Deep Thought, his voice regaining its accustomed
declamatory tones. "A computer whose merest operational
parameters I am not worthy to calculate - and yet I will design
it for you. A computer which can calculate the Question to the
Ultimate Answer, a computer of such infinite and subtle
complexity that organic life itself shall form part of its
operational matrix. And you yourselves shall take on new forms
and go down into the computer to navigate its ten-million-year
program! Yes! I shall design this computer for you. And I shall
name it also unto you. And it shall be called ... The Earth."

Sorry, but HHGTTG is one of my favourite works of fiction. Please forgive me for indulging my passion.
