A Former Prankster's Warning: AI Experts Are Sowing Fear Irresponsibly

Cantrill argues such extraordinary claims lack evidence and that domain experts must not abuse public trust by spreading fear.

That is, if you have a newborn, their claim is that there is a greater than ten percent chance that your child will somehow perish at the hands of AI before they enter middle school.
