Working within Baars' global workspace theory Barthelmess, Furbach, and Schon argue* that the Hyper reasoning system, with ConceptNet as its knowledge base, is conscious. While I agree with much of this I do believe there are different degrees of consciousness. I have also argued** that consciousness is a collection of processes, not one single thing. Hyper and ConceptNet does not have a notion of self*** nor does it have all 10 of Hobson's "functional components".****
I don't think that consciousness is as difficult as the "hard problem" people would have us believe. On the other hand I don't think that Hyper-ConceptNet is as fully conscious as A.s.a. H. is.*****
The attention issue is part of dealing with the curse of dimensionality. Its a problem that must be faced by any machine trying to operate in a large state space.

**** For example, it seems to lack orientation, emotion, and values.
*****But ConceptNet is a large knowledgebase of almost 3 million axioms in first order logic!
