Kurtzeil's The Singularity is Near - I recently picked up the book for the second time, after initially buying it when it first came out. I've put it down again. I don't know if it's the way it's written, the posturing, or what? I get and accept the concepts, but it just feels so hand-wavy and...I dunno. Anybody else have similar reaction?
