I can't say I disagree. But with (reportedly) an A380 carrying 500 km of wiring and a 737NG 67km of wiring, there's a strong incentive to reduce that weight.

Just wait until some bright boy comes up with a plan to eliminate ALL the wiring weight, by simply transmitting all flight control commands to the control surfaces (and everything else) via Bluetooth™ or some such.
