... The Borg thrive for "perfection".
Did you ever think this was a lame motivation? I thought it was lame ... one of those ridiculous notions introduced by the writing staff on
Voyager, it no doubt sounded cool at the time, but it hardly makes sense as a species motivation. At their introduction, they sought unique technology to add to their own enhancement. Later, the focus became "biological and technological distinctiveness". That was a healthy tool-user's interest exaggerated to unhealthy extremes by the Borg Collective. It made them both menacing and logical. But "perfection"? What is that beyond an aesthetic pursuit? Perfection is ultimately a subjective evaluation, unless you're talking about physical quantities (like a perfect vacuum).
