Re: V'Ger origins: Borg or not?
No. Not everything has to be connected to everything else. V'Ger was found by a race of beings on a machine planet after traveling through a quantum singularity. Everything about V'Ger's journey back to Federation space gives the impression that this race was different from the Borg. Otherwise, the writers would have found a way to connect the two after the Borg showed up in TNG. That Shatner decided they were one and the same doesn't matter because his books aren't canon.
