There is a reputation, a certain line of opinion that holds science fiction to be that form of literature which abandons human reality in favor of the theoretically abstract. And while I would argue the majority is not per se, indeed there are numerous examples to support the perspective. Straddling the fence in frustrating and engaging fashion is Clifford Simak’s Why Call Them Back from Heaven? (1967).
The Forever Center is an Adam Smith dream come true. Storing frozen, dead bodies for a future time when the universe is ready for teeming billions of immortals, they have likewise convinced these “stockholders” to let the Forever Center handle their finances while in waiting. Accumulating a majority of the world’s wealth in the process, they are the corporation of corporations—the mother of them all. Their future selling point keeping them somewhat honest, a newspaper headline threatens to blow them wide open, however: the technology for immortality they claim to own may not actually exist.
