Ethan Mollick on Blocking AI Training Data Use

Ethan Mollick, associate professor at Wharton and author of Co-Intelligence, stated that users can stop their data from training models by disabling the relevant option inside OpenAI and Claude. He added that this step is separate from privacy settings. Mollick also pointed to open weights models as another route, while noting that those models will encounter the same data issue once they advance. The comment appears as a reply in an ongoing discussion about AI systems.
