Science-fiction writers make the best seers. In the late 1950s far-sighted Isaac Asimov imagined a sunny planet called Solaria, on which a scant 20,000 humans dwelt on far-flung estates and visited one another only virtually, by materializing as “trimensional images”—avatars, in other words. “They live completely apart,” a helpful robot explained to a visiting earthling, “and never see one another except under the most extraordinary circumstances.”
We have not, of course, turned into Solarians here on earth, strictly limiting our numbers and shunning our fellow humans in revulsion. Yet it’s hard not to see some Solarian parallels in modern life.
