I liked the ideas in Blindsight more than I liked the book. The writing is heavy-handed (trying to be gentle here), especially given how interesting the underlying questions were.
Anyone who gets that far into the book doesn't need to have their hand held that much. I get that it's the entire point of the book, but everything until this point has been a challenging read.
Personally, I think it might have been interesting to rewrite the whole thing such that conclusion is ambiguous.
