Ungrowth wasn't talked about in the novels. I remember the opposite complaint: that the overly strict implementation of the Three Laws turned humanity into kittens, with the wireheads at the extreme. Ungrowth sounds almost as bad as Peer's arbitrary obsessions in Permutation City.
Holding all other implementation details equal, Lawrence's insistence that PI not look into people's brains results in a much better world than not. I get the impression that Roger thinks his genie could have handled people better if it analyzed them that deeply.
This is Roger's article on Singularity issues, connecting his MOPI novel to how things might/should happen.

(Roger is clearly aware of SIAI ideas and has referenced Eliezer in some of his posts)
