We are the Beige Borg. You will be decolorized. We will not add your distinctiveness to our own. Your culture will become bland like us. Resistance is boring.
So this might make the borg less threatening, but I feel like it would infuriate these explorers. ‘What do you mean you don’t want to talk to us anymore’?
The sphere is the most efficient use of volume in space. Rectangles are only convenient for humans, and the Borg should not be concerned about convenience.
If the Borg were really about efficiency, they'd build spheres. But spheres are more boring, which comes back to my original point.
Why am I so fascinated with it, it's so warm, makes me feel... Happy? I must study it more. The cravings of it are getting out of control, I have to make a golden cube sculpture. With anything around me. Even dirt. Praise the cube. Hail the cube.
