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.
I searched the posts but didn't find a great deal of relevant information. Has anyone taken a serious crack at it, preferably someone who would like to share their thoughts? Is the material worthwhile? Are there any dubious portions or any sections one might want to avoid reading (either due to bad ideas or for time saving reasons)? I'm considering investing a chunk of time into investigating Legg's work so any feedback would be much appreciated, and it seems likely that there might be others who would like some perspective on it as well.
