This is really depressing to me. I think this is abusive.

Your son has no concept of the implications of his body, face and identifying features being used here. He has no ability to opt-out, refuse consent, and avoid his data (biometric features) being swooped up in a data-centers for further training, further data collection & further monetization.

Your son didn't agree to the privacy policy of OpenAI. This is an extremely high level of disrespect to a person you created.
