I suspect that for the vast majority AIs, either they do not have the capacity to be a threat to us, or we do not have the capacity to be a threat to them. There may or may not be a very thin window in which both sides could destroy the other if they chose to but even then a rapidly self improving AI would probably pass through that window before we noticed.
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.
