So, basically all you said in that entire paragraph is "I don't think it
will work" because "the local learning mechanisms won't take into account
the level of complexity of the resulting learned content"
Well, it seems pretty obvious that, if you plan to design an intelligent
learning mechanism, it must be a goal driven mechanism using such processes
as to maximize the limited complexity available for computation. Clearly you
have no alternative but to design such a learning mechanism as to operate on
a tightly bounded level of complexity, as opposed to such a mechanism that
operates on an unbounded level of complexity; because this is intractable.
The "generality" of the "cross domain learning" must be implicit in the
learning mechanism, not a feature process of the algorithm (=unbounded
complexity).
