The aim of this paper, rather than attempting to present one coherent strategy for
reducing existential risks, is to introduce a variety of possible options with the
goal of broadening the discussion and inviting further investigation. Two themes
appear throughout: (1) the proposed approaches for risk reduction attempt to avoid
the dangers of centralized “solutions,” and (2) cybersecurity is not treated as a
separate risk. Instead, trustworthy cybersecurity is a prerequisite for the success
of our proposed approaches to risk reduction.
