My original website started as a link collection to all interesting webpages – actually doable when I started in the early 90s, but soon of course totally inadequate despite growing into a thicket of links.
Future of Humanity Institute – this is where I work. We try to understand what really matters for the future of humanity: crucial considerations, existential risk, radical emerging technologies, how to think about strange and uncertain things.
Oxford Uehiro Centre for Practical Ethics – I am also associated with this centre, mostly in regards to bioethics.
MIRI (Machine Intelligence Research Institute) – Making AI safe.
Future of Life Institute – Our American counterpart.
Centre for Effective Altruism – Doing good on an industrial scale.
Center for Applied Rationality – Getting smarter and saner.
Centre for the Study of Existential Risk – Our Cambridge counterpart.
LessWrong – Not just a rationalist community, but discussions about many deep topics.
Practical Ethics – Ethics in the News – Blog I sometimes contribute to.
Oxford Martin School – James Martin’s amazing creation, trying to solve the Big Problems.
Eclipse Phase – Terrific roleplaying game about a postsingularity future.
