Those who've watched Star Trek: The Next Generation will know the Borg as a race of mindless cybernetic drones bound by a collective consciousness and lacking any trace of individuality. The Borg travel across the galaxy, forcefully assimilating any civilizations they encounter into their collective. As such, they must be mortal enemies of humanity, since our sense of self (and by extension our liberty) is a large part of what makes us human -- or so we believe.
What I find so intriguing about the Borg is the fact that they can communicate so efficiently. In essence, all their minds are directly connected to each other via some kind of super internet. The most optimistic among us believe that we might also achieve such an ability within our lifetimes.
I don't think anyone would argue that explosion of information made available by the internet is a bad thing. But humans are limited both by how much information we can send, receive and manage, as well as by the amount of computation or reasoning we can perform (not to mention all the inherent biases embedded in our neural hardware). It's why advertising companies and politicians care so much about marketing slogans and grabbing mind share. It's why we can benefit from playing games with indirect social and status signaling. It's essentially why we still have so much misunderstanding in this world.
While we shouldn't hope to completely eliminate our limitations (as that would violate our current understanding of physics), there's no reason to think that we cannot create a more efficient and freer society by making it easier and faster to communicate and organize information. In fact, we are already experiencing a change in attitude regarding what we take for granted communication-wise. For instance, I already have developed an intrinsic feeling of being connected to others through the internet. When GMail went down this past summer, I actually felt lonely (probably much like how Hugh felt in Star Trek episode "I, Borg"). Whenever I don't have my phone with me, I often feel somehow naked or incomplete.
Contrary to how the Borg are portrayed, expanding communication bandwidths will likely increase our diversity of thought rather than suppress it. I think the general principle of having robustness (e.g., promoting diversity) is a lesson that's been well learned (with notable exceptions). Forward thinking companies such as Google (where I interned this past summer) and Microsoft (3 summers ago) consistently emphasize diversity of thought and creativity in problem solving. Having a more connected society will make it easier for the good ideas to surface.
There are, of course, concerns over whether we could or should integrate our minds with "machines". One reason why we're supposed to find the Borg so repulsive is due to their cybernetic nature. Rather than debating what it means to be "human", I think it's sufficient for this discussion to note that such technologies can be a life-changer for people suffering from paralysis. In addition, there is still much left to accomplish with non-invasive interfaces (such as our phones), so we still have a ways to go before we need to cross that tricky bridge of having immersive virtual environments.
