In the Q Who episode, Guinan tells Picard that humanity’s encounter with the Borg came "much sooner than it should have". She also says if humanity had met the Borg when they were supposed to, a relationship of sorts could have been established. She also says that since they are now aware of humanity, they will be coming.
How can the Borg just be aware of humanity now, when they had scooped up the human and Romulan colonies along the Neutral Zone? Guinan made it seem as if humanity wasn't supposed to meet the Borg for a long, long, long time, but the Borg were already only a month or two or so travel from Earth and Romulus.
So let's say we weren't supposed to meet them for 200 years, how would we be technologically ready to face them even that far in the future? From what I've seen, the Federation just improves on its basic tech which the Borg would have undoubtedly just adapted to in only a few shots. Were the Borg just that uninterested in us until Q flung the ship 7,000 light years away?
