The script of the first Matrix movie is almost flawless, but one theme that doesn't hold water is the statement that the machines' need of humans are as an energy source by extracting waste heat and "bioelectricity". This breaks the suspension of disbelief somewhat*.
Since we know later on that Morpheus has incomplete information (for instance, the age of the Matrix) and since I'm sure the Wachowskis have added multiple layers to their trilogy and associated canon:
Has the Matrix canon or the Wachowskis ever suggested that the machines' co-dependence on humans is psychosocial instead of energy based?
By this I mean, I've gained an strong suspicion from various dialog in the Matrix trilogy and Animatrix shorts that the machines at some level want the survival and carefully managed existence of humans in order to define themselves (existential loneliness?) and the energy requirements are a self-rationalizing smokescreen - Has this implication been suggested or explicitly raised in the canon or by the Wachowskis in interviews?
* In trilogy with anti-grav sentinels, oracles and CPR from inside the Matrix, it's little odd that this breaks the suspension of disbelief, but there you have it.
This question differs somewhat from Why do the machines keep humans alive if they have nuclear reactors? in that I'd like to know what precisely, if anything, in the canon script or directorial interviews affirms the idea that the machines want humans in the matrix because of psychosocial co-dependence instead of any functional needs (be it electricity or organic brain power).
