For non-chess players - imagine if Geoffrey hinton used AI detectors (GPT zero, pangram etc) to accuse and punish people of using AI in their writing and bad mouth them publicly. That's what kramnik (former world chess champion) did to Danya and other players. I miss Danya.
To my knowledge, Pangram has a very low false positive rate approaching zero. (False negative is another matter.) I’m not sure that’s what you want to use as the analogy here? (I don’t know much about this Kramnik situation.)
How did he punish them?
