Designing algorithms to return definitive results and then getting duped by conspiracy theorists is embarrassing; doing the same and getting pwned by the hapless stupidity of large language models is malpractice.
IMO this is not simply a matter of Google's algorithms being no good. What's going on here is that Google is playing a losing game by trying to extract true information from the web algorithmically. Why would Google choose to play a game it could only lose?
