I agree completely with what Zig said about the human element. I think the harvesters and all the other AIs floating about are simply one too many - robots may be a sci fi element, but this isn't just any sci-fi. It's the Freelancer universe. Freelancer robots are simple waiters, equipment dealers and workers on stations unsuitable for humans. They are not sentient, intelligent AI beings, they are not war-mongering fighters, nothing like that.
