In this paper, I present a solution to the Doomsday argument based on a third type of solution, by contrast to on the one hand, the Carter-Leslie view and on the other hand, the Eckhardt et al. analysis. I begin by strengthening both competing models by highlighting some variations of their ancestors models, which renders them less vulnerable to some objections. I describe then a third line of ...

The first questions facing the development of artificial intelligence (AI), addressed by all three authors, are how likely it is that humanity will develop an artificial human-level intelligence at all, and when that might happen, with the implication that a human-level intelligence capable of utilizing abundantly available computational resources will quickly bootstrap itself into superintelli...
