Welcome to the forums Majestic!
I looked at this yesterday, and had the thought that it will get moved to the P/R forum eventually. Hopefully I will not stray too far into it.
I tend to value what Kurzweil says, and think something like what he feels will happen. That said, I'm with Majestic in that it will cause the issue of stratification in a new category and/or level. To me, it will solve less problems than what problems it creates- societal, and mores/beliefs. And Rumborak it was nice to see your insight, considering your career. I figure the guy knows some stuff, but is a best seller and therefore probably has some zealous appeal at this point!
Then there is also the threat issue. If the AI was in control, I wouldn't fault it for making decisions ala WallE, Terminator2, I, Robot and so on.
