Some more excerpts: not all humans of the industry are optimistic,
"The computer designer and venture capitalist William Joy, for example, wrote a pessimistic essay in Wired in 2000 that argued that humans are more likely to destroy themselves with their technology than create a utopia assisted by superintelligent machines."

And some worst fear is the Moses Syndrome being just one generation before:

"Indeed, despite this high-technology heartland’s deeply held consensus about exponential progress, the worst fate of all for the Valley’s digerati would be to be the generation before the generation that lives to see the singularity; Kurzweil will probably die, along with the rest of us not too long before the ‘great dawn,’ ” said Gary Bradski, a Silicon Valley roboticist. “Life’s not fair.”

Interesting. I do not see, however, a need to regress to the human proclivity towards eternalism or nihilism. The problems associated with the 'Singularity' are conceptual and linguistic (though what makes it interesting, I feel, is that the conceptual and linguistic appear to be changing their forms at a tremendous rate so that our own cognitive skills, and understanding of these skills, present philosophical challenges that are new and do seem to coincide with the Singularity's emerhence).
