Captain Jean-Luc Picard of Star Trek: The Next Generation, after his assimilation by the Borg.
Whenever I see people walking down the street wearing those little Bluetooth headsets, I think of the Borg.
Okay, really... first I think that they must be crazy people, because when I grew up, if you saw someone walking down the street alone talking, it meant that they weren't getting the right meds.
But then once I do notice the headset, I think Borg.
To summarize the concept of Borg quickly, I'll excerpt a passage here from the page for Borg on Wikipedia, as I trust Trekkers to vehemently enforce the accuracy of that entry -- and if they don't, well, there's not a whole lot at stake here. It's science-fiction, folks. (Or is it?)
The Borg are a fictional pseudo-race of cybernetic organisms depicted in the Star Trek universe. The Borg have become a symbol in popular culture for any juggernaut against which "resistance is futile." The Borg manifest as cybernetically enhanced humanoid drones of multiple species, organized as an interconnected collective, the decisions of which are made by a hive mind, linked to subspace domain. (...) They operate solely toward the fulfilling of one purpose: to "add the biological and technological distinctiveness of other species to their own" in pursuit of perfection. This is achieved through forced assimilation, a process which transforms individuals and technology into Borg, enhancing, and simultaneously controlling, individuals by implanting or appending synthetic components.
In the Star Trek universe, assimilation by the Borg is generally assumed to represent an enhancement of individual capabilities. But the price of enhancement is control, the subjugation of all individual wills to a collective mind, which runs counter to most of our cultural notions about what it means to be human.
