"Life After Life, Death After Death"

In Poul Anderson's "The Voortrekkers" (Explorations, New York, 1981) (see previous post), the transferred neural patterns visit:

Sirius, which has no planets;

Tau Ceti, where they send organic bodies to explore a planet;

Sigma Draconis, where the organics meet intelligent beings;

36 Ophiuchi B, where they explore a planet;

82 Eridani, where a substance in native food releases "'...an enzyme which destroys niacin in the bloodstream...'" (p. 172) so that the organics cannot survive.

Over the centuries, they give Earth:

the ability to travel swiftly between stars in organic bodies and to colonize uninhabited planets;
an end to sickness, insanity and old age;
cultural input from many races, leading to an unending renaissance;
vast wealth for each individual;
growth towards wisdom and an end of strife.

They visit Earth, return to space and remember their original lives.

The Voortrekkers

In Poul Anderson's "Epilogue," machines have been naturally selected for consciousness and intelligence whereas, in his "The Voortrekkers" (Explorations, New York, 1981), machines have been programmed with human psychoneural patterns. Thus, "The Voortrekkers" addresses issues that are treated at greater length in Anderson's Genesis and Harvest of Stars Tetralogy.

In "The Voortrekkers," for slower than light extra-solar exploration:

a complex and dynamic human psychoneural pattern is scanned and recorded, then transferred to a photonic-electronic matrix, thus producing a conscious, motivated, self-programming machine, needing no life support, that "'...can be switched off in transit...'" (p. 159);

on arrival in another planetary system, the neural pattern can be transferred to a molecular-organic matrix, thus producing a human being who can explore a planetary surface and test its habitability.

When the original consents to be scanned and recorded and to give cells for chromosome templates, he knows that he will continue to live on Earth or in the Solar System and will eventually die there. It makes no sense for him to wonder whether he will be the one who wakes up in a spaceship entering another planetary system. Yet when the transferred neural pattern becomes conscious, it will think, "I am the one who has woken in the spaceship..."

Is this, rather than human beings traveling faster than light, the real future for interstellar travel?
