The Borg don't have that problem. Every drone knows everything the hive knows and the hive never forgets. Therefore every drone knows which cable to replace, should the need arise.
Or trust me I have. Imagine if you will a house from the 1930s with the internet cable running from the opposite side of the house as the router. However the wire is deliberately put through as many rooms as possible on the way to the router and super glued into place as though it's fine to trip on a wire 5 times to get to a room.
You have the accumulated memories of trillions of prior drones, including the ones who built that mess in the first place, so you already know what each cable does and where it goes.
A starship would more similar to a mine than a server room. What if the hydraulics pipe is broken and needs replaced, but the electric line and compressed air hose are tangled around it? Even with perfect knowledge and memory it makes the repair last longer.
I dunno, I always thought it was meant to mimic organics.
"Cable management" inside the human body is horrendous. So it felt like in the mixing of machine and biology, the machines had to become more biological in the way they worked to function properly in tandem with the Borg biology.
That's exactly it. Cable management is a top-down design philosophy. The Borg are a collective that organically integrates biological, mechanical, electronic, and any other systems that they find useful--it's quite literally the polar opposite of a top-down design philosophy.
It would be more surprising if the Borg had tidy cable management, because that implies some hierarchy. Actually, the Borg cubes are a little out of place in that regard. Spheres or fractal-ish structures would make more sense.
I don't know, the drones in First contact didn't had an issue working on the hull of the Enterprise. But Enterprise hull might be an edge case, as in "Not really Borg but soon"-technology.
On the other Hand, the Borg assimilate anything they get their cable management on (eg. the doctors mobile holographic emitter).
But I don't really know much of the deeper Borg lore.
You will be assimilated. (and forced to wire things as directly as possible because that is more efficient as long as it doesn't hinder future endeavors)
Wireless power transmission is bretty shitty in practice. Anything transmitted wirelessly will be occupying that space in whatever scifi spectrum they're using. So for high speed data transfer also they will have much much more spectrum. To use within each each cable.
No matter what companies will tell you, cables is always faster and more efficient than wireless, there's physical reasons foe that. Drones are linked to others and to cubes wirelessly because they need to do stuff and move around. Vessels are linked wirelessly with each other for obvious reasons. But there is likely an elabration center in each vessel and it's going to be cabled to every alcove and every sensor and actuator of the ship
The Borg are played up to be this hyper-advanced ruthlessly efficient hive mind, but they nearly never act like it. Case in point: Seven of Nine has two tits and one eye.
