We attempt to justify the use of synthetic biology in response to the climate crisis, based on the premise that it is impossible to avert runaway climate change without sequestering sufficient greenhouse gases (GHG), which could only become possible through Negative Emissions Technologies (NETs). Then, moving from a consequentialist standpoint, we acquiesce to how the consequences of using NETs through synthetic biology are preferable to the catastrophic consequences of runaway climate change. In conclusion, we show how our analysis of synthetic (...) biology resonates with a zoecentric view of climate science and ethics. (shrink)

A major approach to the ethics of artificial intelligence is to use social choice, in which the AI is designed to act according to the aggregate views of society. This is found in the AI ethics of “coherent extrapolated volition” and “bottom–up ethics”. This paper shows that the normative basis of AI social choice ethics is weak due to the fact that there is no one single aggregate ethical view of society. Instead, the design of social choice AI faces three (...) sets of decisions: standing, concerning whose ethics views are included; measurement, concerning how their views are identified; and aggregation, concerning how individual views are combined to a single view that will guide AI behavior. These decisions must be made up front in the initial AI design—designers cannot “let the AI figure it out”. Each set of decisions poses difficult ethical dilemmas with major consequences for AI behavior, with some decision options yielding pathological or even catastrophic results. Furthermore, non-social choice ethics face similar issues, such as whether to count future generations or the AI itself. These issues can be more important than the question of whether or not to use social choice ethics. Attention should focus on these issues, not on social choice. (shrink)

Cost-benefit analysis (CBA) evaluates actions in terms of negative consequences (costs) and positive consequences (benefits). Though much has been said on CBA, little attention has been paid to the types of values held by costs and benefits. This paper introduces a simple typology of values in CBA and applies it to three forms of CBA: the common, money-based CBA, CBA based in social welfare, and CBA based in intrinsic value. The latter extends CBA beyond its usual anthropocentric domain. Adequate handling (...) of value typology in CBA avoids analytical mistakes and connects CBA to its consequentialist roots. (shrink)
