How interesting - I've been leaving GEB on the coffee table in hopes that I might pick it up and start it again (made it halfway about 10 years ago) but now I wonder whether I ought to pick this up. Thanks for letting us know.
If the content was concise or written in the style of say Persig, Neal Stevenson or Ray Bradbury, I could stomach it.
Then again even worse is Ray Kurzweil who manages to do a GEB with far less content and that content is dubious and contrived rubbish.
"The Mind's I" remains my favourite, by far.
