Our verdict
InaccurateSources explicitly state Sankar provided no names, evidence, surveys, or data to support the claim. It was presented as an unverified anecdote. Sankar presented this as an example of problematic 'mass psychosis' and 'social delusion' in AI discourse, using it as criticism rather than endorsement of actual behavior.
