Published in 1985, “More Than the Sum of His Parts” was set in the then-distant future of 2058. “It seemed a reasonable time frame, when we were somewhat more optimistic about space industrialization,” Haldeman says, “although the waldo technology is wishful thinking, or arm-waving—I didn’t have any actual technological rationale for it happening that soon, or ever. The waldos themselves were inspired by the story ‘Waldo,’ by Robert Heinlein. The idea of smaller and smaller waldos building their miniaturized successors came from the notions about self-replicating ‘von Neumann’ machines that were cutting-edge techno-dreaming at the time.”

This is a post-poverty utopia where everybody lucky enough to be plugged into the society’s opportunities—the passengers or if you prefer “pilots” of the arvies—gets to do whatever the heck they want to do with their lives, indulging their slightest whims via the bodies whose wombs they occupy. I left unexplained what criteria determine who gets to enjoy all of this world’s vast opportunities and who becomes an enslaved recreational vehicle; that decision is made, from standards you and I can only guess at, long before any fetus is granted the gift of adult awareness. There must also be genetic and medical issues involved far beyond us. But no doubt, if some zygote possesses genetic gifts that promise vast talent in athletic pursuits, that’s a quality that would render their future body very very much in demand as athletic gear for some fetus interested in enjoying the ride from the safety of the amniotic fluid.

“I had a story I really wanted to tell about a child being raised in isolation, ignorant of an apocalyptic infection raging in the outside world, so my approach to ‘Patient Zero’ was probably something like ‘A spoonful of science helps the narrative go down.'”
