Suggestions for a presentation on FAI?

Next week I’m going to be doing a 10-15 minute presentation on Friendly AI to a local group of programmers. They’re already familiar with concepts such as the singularity. My basic plan is to cover what FAI is, why it’s important, and why it’s a hard problem, based on the material on this site.

Does anyone have any specific suggestions of things that should be included, questions that I might need to answer, etc?
