as always lesswrong posters continue to be lost in the sauce

Since I discovered and started reading Lesswrong a couple years ago, I keep seeing dismissive or sneering comments across the (technical) internet, usually with very little substance - like this one (what does it even mean? I find the article rather reasonable and on point). I know that yudkowski's more recent stance is controversial (I haven't started reading his work on how AGI will kill us all so I'm suspending judgement ), but is there a valid reason for the widespread smugness or is it just a bandwagon effect?
