{Reference Type}: Journal Article {Title}: Life-Suspending Technologies, Cryonics, and Catastrophic Risks. {Author}: Sauchelli A; {Journal}: Sci Eng Ethics {Volume}: 30 {Issue}: 4 {Year}: 2024 Aug 9 {Factor}: 3.777 {DOI}: 10.1007/s11948-024-00498-w {Abstract}: I defend the claim that life-suspending technologies can constitute a catastrophic and existential security factor for risks structurally similar to those related to climate change. The gist of the argument is that, under certain conditions, life-suspending technologies such as cryonics can provide self-interested actors with incentives to efficiently tackle such risks-in particular, they provide reasons to overcome certain manifestations of generational egoism, a risk factor of several catastrophic and existential risks. Provided we have reasons to decrease catastrophic and existential risks such as climate change, we also have a (defeasible) reason for investing in developing and making life-suspending technologies (more) widespread.
