The LessWrong 2.0 team conceives of itself more broadly as an organization attempting to build community, culture, and technology which will drive intellectual progress on the world’s most pressing problems.
Thank you! That page addresses the question only in the one quoted sentence, "In 2015-2016 the site underwent a steady decline of activity leading some to declare the site dead.". This page, which I found via the link in the parent, says much more:
I suspect it's connected to the political rejection of post-modernism (in its actual meaning, not the politically loaded meaning) and with it the Enlightement ideas of reason/rationality (replaced by 'winners' - brazenness and aggression), fact (replaced by 'post-truth'), intellect, universal rights and humanitarianism (replaced by nationalism and reactionaryism), and through those things the power and obligation of humans to better their world and themselves. That rejection was widely normalized, I suspect, in the election of 2016, IME. A problem with talking about these things is a factual basis.
