For those interested in more seriously exploring the issues of Artificial General Intelligence and the Singularity, I’d like to recommend the following writings, in the following order:

Creating Friendly AI
Levels of Organization in General Intelligence
Artificial Intelligence as a Positive and Negative Factor in Global Risk
Coherent Extrapolated Volition
Knowability of Friendly AI

If you make it through these five documents, please do email me and tell me what you think. One of the biggest barriers to sophisticated Singularity discourse is simply that most people do not take the time to look at the existing literature in detail.
