Is there a wiki or website that keeps track of things related to the Great Filter?
I guess I'm looking for something that enumerates all the possible major filters, and keeps track of data and arguments pertaining to various aspects of these filters.
I'm not aware of any such thing. It would be nice to have. There was an earlier Boston meetup a few years ago where a few of us tried to brainstorm future filters but we didn't really get anything that wasn't already known (I think jimrandomh mentioned that there's been similar attempts at other meetups and the like). The set of proposed filters in the past though is large. I've seen almost every major step in the evolution of life being labeled as a filter, and there's sometimes reference class tennis issues with them, especially when connected to developments that aren't as obviously necessary for intelligent life.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
