I think more downvoting being the solution depends on the goals. If our goal is only to maintain the current quality, that seems like a solution. If the goal is to grow in users and quality, I think diverting people to a real-time discussion location like Discord could be more effective.
Eg. a new user coming to this site might not have any idea a particular article exists that they should read before writing and posting their 3 page thesis on why AI will/wont be great, only to have their work downvoted (it is insulting and off-putting to be downvoted) and in the end we may miss out on persuading/gaining people. In a chat a quick back and forth could steer them in the right direction right off the bat.
I’m not saying “the experts can be wrong” I’m saying these aren’t even experts.
Pick any major ideology/religion you think is false. One way or another (they can’t all be right!), the “experts” in these areas aren’t experts, they are basically insane: babbling on at length about things that aren’t at all real, which is what I think most philosophy experts are doing. Making sure you aren’t one of them is the work of epistemology which The Sequences are great at covering. In other words, the philosopher experts you are citing I view as largely [Phlogiston](https://www.lesswrong.com/posts/RgkqLqkg8vLhsYpfh/fake-causality) experts.
