Comparing frameworks for AI development allows us to see trends and reflect on how we are conceptualizing, interacting with, and imagining futures for AI. Recent scholarship comparing a range of AI frameworks has often focused methodologically on consensus, which has led to problems in evaluating potentially ambiguous values. We contribute to this scholarship using a rhetorical perspective attuned to how frameworks shape people’s actions. This perspective allows us to develop the concept of an “AI mainstream” through an analysis of five (...) of the highest-profile frameworks, including Asimov’s Three Laws. We identify four features of this emerging AI mainstream shared by most/all of the frameworks: human-centered design focus, abstraction-oriented ethical reasoning, privileged authorship, and ahistorical regulatory justifications. Notably, each of these features permeates each framework, rather than being limited to a single principle. We then evaluate these shared features and offer scholarly alternatives to complement and improve them. (shrink)
