Yes, I've only seen it after posting this one. It is one of a few resources that recently emerged that satisfy my idea of a concise and easy roundup. So far you had to read many papers or all of the sequences to be able to implicitly conclude that you should support the SIAI. I don't think that approach works very well. If people are in doubt after reading the following resources, then you can still tell them to read LW:
Someone should put the above content together and maybe add a few more good arguments, like this one:
An AI might go from infrahuman to transhuman in less than a week? But a week is 10^49 Planck intervals - if you just look at the exponential scale that stretches from the Planck time to the age of the universe, there's nothing special about the timescale that 200Hz humans happen to live on, any more than there's something special about the numbers on the lottery ticket you bought.
If we're talking about a starting population of 2GHz processor cores, then any given AI that FOOMs at all, is likely to FOOM in less than 10^15 sequential operations or more than 10^19 sequential operations, because the region between 10^15 and 10^19 isn't all that wide a target. So less than a week or more than a century, and in the latter case that AI will be trumped by one of a shorter timescale.
Now only very little remains and I got much of what I asked for :-)
Here is another example of an outsider perspective on risks from AI. I think such examples can serve as a way to fathom the inferential distance between the SIAI and its target audience as to consequently fine tune their material and general approach.

This shows again that people are generally aware of potential risks but either do not take them seriously or don't see why risks from AI are the rule rather than an exception. So rather than making people aware that there are risks you have to tell them what are the risks.
