“Eliezer’s Lost Alignment Articles / The Arbital Sequence” by Ruby

Note: this is a static copy of this wiki page. We are also publishing it as a post to ensure visibility.
Circa 2015-2017, a lot of high quality content was written on Arbital by Eliezer Yudkowsky, Nate Soares, Paul Christiano, and others. Perhaps because the platform didn't take off, most of this content has not been as widely read as warranted by its quality. Fortunately, they have now been imported into LessWrong.
Most of the content written was either about AI alignment or math[1]. The Bayes Guide and Logarithm Guide are likely some of the best mathematical educational material online. Amongst the AI Alignment content are detailed and evocative explanations of alignment ideas: some well known, such as instrumental convergence and corrigibility, some lesser known like epistemic/instrumental efficiency, and some misunderstood like pivotal act.
