with a gene that
other people get naturally"—and "Type II"
enhancements, "those that have
not appeared previously within the human population."
Silver continues: "The use of genetic enhancement could
the gap between `have's' and `have-not's' in the world. The
emerge initially between classes within a society. But, if the
reprogenetic technology follows the downward path taken by other
technologies like computers and electronics, it could become

"When this happens, the social advantage that wealthy
maintain could be converted into a genetic advantage. And the
