i.Offers a new interpretation of "playing God" arguments in technology ethics ii.Provides a conceptual apparatus for engaging in debates over the morality of new or emerging technologies in a critical manner through the constructive lens of "playing God" arguments iii.Sketches a conceptual framework consisting of an argumentation scheme for "playing God" arguments along with Critical Questions iv.Analyzes "playing God" arguments as they are made in debates over the ethical development and deployment of new and emerging technologies, such as solar geoengineering, Artificial Intelligence (AI), autonomous vehicles, autonomous weapons, and more v.Argues that "playing God" arguments allow us to assume an intermediate and critical attitude between the extremes of hype and panic, or techno-optimism and techno-pessimism vi.Provides an approach to the governance of new or emerging technologies in ways that might help to increase our control over, improve our understanding of, and prevent our misuse or abuse of such technologies vii.Bridges the fields of informal logic, argumentation theory, and technology ethics through a careful analysis and evaluation of use cases of new or emerging technologies, such as solar geoengineering, Artificial Intelligence (AI), autonomous vehicles, and autonomous weapons, and their associated "playing God" arguments.
