Whoa, hold on. Data was an android, but one that is meant to mimic an individual being. He may have been a form of AI, but he is no more than just an advanced human. And yes, the ship couldn't function without computers - but they were traditional (but futuristic) computers manned by people, with AI guided by people - not AI that controlled every aspect of their lives. I think when people think of AI, and the fear that comes with it - they imagine the type of AI that takes over human function and renders them unimportant. Also, the Borg didn't fully embrace AI. They were a collective, linked together by technology. You can view them as more or less a singular entity with many moving parts that communicated over subspace, striving to achieve perfection (in their own eyes). As a consequence, they seek to assimilate (thus parasitizing their technological advancements for their own) or eradicate other species in an attempt to improve the Hive.
