H. Beam Piper’s 1963 The Cosmic Computer is a standalone science fiction novel. It’s set in Piper’s Terra-Human future history, in the last days of the Federation.
Conn Maxwell returns from Terra to his backwater homeworld, Poictesme, armed with hard-won knowledge. The family friends who pooled resources to pay for Conn’s education did so in the hope that while on Earth, Conn would uncover the secret location of Merlin, the fabled supercomputer that many believe allowed the Federation to triumph over the secessionist System States Alliance. With Merlin’s help, surely the investors could learn how to kickstart Poictesme’s moribund economy.
What Conn learned was that Merlin was not just legendary. It was a myth. There would be no all-powerful supercomputer to guide Poictesme to prosperity.
When Conn returns to his homeworld, he lies to his friends and backers. He claims to know how to find Merlin. This isn’t just an attempt to spare his friends or evade responsibility for the failure. He wants to use the belief in Merlin to inspire his world to take the steps that will rebuild its economy.
