The thesis is quite readable and I found it valuable to sink deeply into the paradigm, rather than have things spread out over a bunch of papers.

The most worthless part of the thesis, IIRC*, was his discussion and collecting of definitions of intelligence; it doesn't help persuade anyone of the intelligence=sequence-prediction claim, and just takes up space.

* It's been a while; I've forgotten whether the thesis actually covers this or whether I'm thinking of another paper.
