It was refreshing to finally have someone acknowledge the fact that a collective mind comprised of the knowledge of trillions of intelligences might not have difficulty reproducing in a manner other that assimilation.
The vague idea that they don't reproduce comes from a line by 7of9 in Voyager that has a very subjective meaning IMO. The idea that can't, that the Borg don't have the ability to reproduce on their own, that just defies onscreen evidence and all manner of reason to me.
Well, just to clarify, I'm pretty sure that what I described in GTTS was not exactly conventional reproduction, more like harvesting gametes from assimilatees and conceiving new drones-to-be in vitro
. And that was following the precedent of the Borg incubation chamber we were shown in "Q Who," an episode written before the concept of assimilation was introduced.
