the inversion

A reflection on 'the inversion' — a phenomenon observed by YouTube engineers around 2013 where bot-generated web traffic threatened to surpass real human traffic. When that threshold is crossed, algorithms trained on the assumption that most traffic is legitimate could flip, misclassifying bots as real and humans as fake. The author frames this as both a societal concern and an algorithmic design challenge, suggesting it demands a new class of algorithm that doesn't fit neatly into classifier, outlier detector, or clustering paradigms.
