Are you aware of the Grey Goo theory?

I think this is what they're basing the Borg on.
It was nanotech that was meant to heal them, cure them and keep them "perfect". That developed beyond their control and infested the planets population.
Thanks for pointing that out as I hadn't read that before. It has the right flavor for sure. I don't think any species would set out to turn themselves into cyborgs on purpose. It is a scenario used by others, the above mentioned Ellison short story, and even Frank Herbert wrote a thinking machine revelation as back story to "Dune."
I think there has been more written now, but I lost interest in "Dune" after the third book.
Cyborgs are interesting because you can use them both ways as heroic beings or villainous ones, although either way they are tragic characters.
The challenge isn’t to come up with a beginning for the Borg, but to be able to make your theory work with Trek canon, and that’s where I think “Destiny” falls short. I don’t think the Borg could have made Kathryn Janeway a Queen, they could have assimilated her, they could have killed her, but they could not make her a Queen. From “First Contact” we find out that the Queen wanted Picard as a companion, but to do so he must give himself freely, it’s not a great jump to assume that Queens have to give themselves freely too.
