The real issue is not Kurzweil, its the idea of Strong AI and a Technological Singularity. I challenge that if the ideas are feasible, then they should be discussed.

Seems like some fall into the trap of relying on famous names, it turns into a 'personality cult' if taken too far.

I admire Hofstadter, brilliant man, and great writer. Though I think he sees the mind as sacred, and if AI were to emulate it, he would loose dignity.
He is also annoyed at software writing music: http://www.miller-mccune.com/culture-society/triumph-of-the-cyborg-composer-8507/

PZ Myers: I have seen his writing on the subject, i have not heard him say anything rational about the idea of a technological singularity, just seems to attack one person who has written about it...please alert me if he has found a knock down argument against Strong AI or the Singularity.

Have not really read what Bruce Sterling has to say. Perhaps someone can outline his arguments against the possibility of Strong AI?

The Pope 'might be' smarter than you, GWB might be also, does that mean you should agree with everything they say?
People who are 'most probably' smarter than you think that it is possible, including Dan Dennit, he just does not think it is 'near' : "Well, I think that the idea of the singularity is, it’s possible and principle of course but I think that the idea that it’s in the near future is just not possible."

Point is, forget hero worship, people should do some proper research for themselves, and make their own rational decision.
