The SL4 mailing list is a refuge for discussion of advanced topics in transhumanism and the Singularity, including but not limited to topics such as Friendly AI, strategies for handling the emergence of ultra-powerful technologies, handling existential risks (planetary risks), strategies to accelerate the Singularity or protect its integrity, avoiding the military use of nanotechnology and grey goo accidents, methods of human intelligence enhancement, self-improving Artificial Intelligence, contemporary AI projects that are explicitly trying for genuine Artificial Intelligence or even a Singularity, rapid Singularities versus slow Singularities, Singularitarian activism, and more. The SL4 list is moderated to maintain list quality (moderation takes place on a poster-by-poster basis, rather than post-by-post). As SL4 is intended to cover new territory in advanced topics, new posters may wish to browse the archives before making their first posts. We explicitly aim to avoid endlessly rehashing the basics. We realize the importance of having forums where newcomers can ask basic questions, but SL4 is not such a forum; some transhumanist lists that are more newcomer-friendly include wta-talk and Extropians. However, all list readers are welcome (you don't have to be familiar with the topics to subscribe - just to post). Join discussion...
