This is precisely what I meant. In some examples the line of reasoning "AI->MNT->we're all dead if it's not friendly" is specifically prefaced with the discussion that any detailed example is inherently less plausible, but adding the details is supposed to make it feel more believable. My whole argument is that I think this specific detail will backfire in the "making it feel more believable" department for someone who does not already believe in MNT and other transhumanist memes.
