Ray is smart and very insightful. His predictions are informed and often durable. I find his self promotional tone, constantly referring to "my" theory and what "I" did, grating and difficult to take seriously. I haven't read much of Kurzweil, but I did meet Aubrey de Gray, who I find to be a similarly toned snake-oil hawking hyper-intellectual self-proclaimed messiah of this new technological religion.

I do find these guys thought provoking and informative, but how they seem to take some sort of credit for advances in technologies simply for predicting their impacts, with self-promotional gibberish, is irritating to say the least.

This article is similarly interesting, but it comes as an attempt to defend his legacy rather than add to the debate. While he makes some strong points that his critics are often ill informed, overall my respect for him has been damaged by his willingness to bend his past words. How can I trust anything he writes in the future?
