There�s hope because you can be turned back into a human.

Yes. We saw with the Seven of Nine character in Voyager that the assimilation process was not irreversible. It was very difficult to reverse and we saw that as well with Captain Picard on the Next Generation in The Best of Both Worlds. He was assimilated and we managed to get him back from the grips of the Borg and return him to his original humanity.

It�s interesting in another sense that the Borg represent some of our greatest hopes and fears, which is why they�re such an effective villain. They represent the dark side of technology, but there is a very hopeful side to this kind of technology as well. For people who are suffering from injuries or diseases that currently cannot be effectively treated by medicine, these sub-microscopic machines may some day be able to address those problems. But, of course, every new technology potentially has a dark side.
