My own view these days is that a wild combination of agents is
probably not the right approach, in terms of building AGI.
Novamente consists of a set of agents that have been very carefully
sculpted to work together in such a way as to (when fully implemented
and tuned) give rise to the right overall emergent structures.
There is one way you can form a coherent, working system from a congeries of
random agents: put them in a marketplace. This has a fairly rigorous
discipline of its own and most of them will not survive... and of course the
system has to have some way of coming up with new ones that will.
In principle, yeah, this can work.
But we have to remember that the biggest problem of AGI is dealing with
severe computational
resource limitations (and, the brain's resources are also to be
considered severely limited, compared
to what naive computational algorithms could easily consume,
mathematically speaking).
The question is whether a "virtual marketplace" is a viable approach to
AGI, in terms of computational
expense...
For instance, Baum's Hayek is an innovative and exciting use of
economics in an AI learning context,
yet the approach seems not to be scalable into anything resembling an
AGI architecture.
Novamente uses economic ideas in some aspects, but mainly just for
allocation of attention (system
resources) among different internal processes.
My strong intuitive feeling is that using a virtual marketplace to
originate a coherent working system from a
congerie of random agents would not be computationally feasible. This,
to me, falls into the same
general category as "build a primordial soup and let Alife and then AI
evolve from it." Yes, these
things can work given enough resources. But the resource requirements
are way higher than for
more direct engineering-oriented approaches.
The brain may well involve some economics-ish dynamics. Energy
minimization and energy
conservation certainly share some common factors with profit
maximization and money conservation.
However, I really doubt the brain relies on emergent market dynamics to
enable interoperation of
its various components. The interoperation of the components was
originated via evolution, and is merely
tuned and minorly adjusted by brain dynamics during the life of the
organism (quasi-"economic" or
otherwise).
