Yes, the Borg Queen installed a nanoprobe replicator module. It's pure chance that Data hasn't accidentally assimilated anyone yet.
I agree. Nobody has a soul. The unfortunate reality is that we all end. Data is just as human as any of us.
If no one has a soul then what exactly did Kirk and Janice Lester transfer to each other's body? Or are you all only defining 'soul' as 'consciousness that survives death'?
Just the later. The consciousness transfer between Kirk and Janice did not dissipate out into the universe. That energy had a body to go to.
I think the implication of the episode is that current Borg technology is able to replace dead neurons in the brain with nanoprobes? And it was able to do so in a 16 hour period. Neelix was expecting to be at the "Great Tree of Life" pretty much immediately after his death. And we know that his neurons had completely degenerated at that point (hence the need for artificial technology to make them work again) So it seems to me that the implication was that Neelix was clinically completely brain dead. It would seem strange that a soul would hang around for 16 hours in a body that has been dead for that long. Nope and nope.
