On the human side, this phrase prompts introspection about how we want our digital footprints treated. Do we prefer ephemeral interactions that leave no trace? Or do we accept that traces exist and demand robust governance—clear purpose-limitation, minimal retention, and meaningful oversight? The answer is seldom absolute. Different contexts require different balances: health systems must retain certain logs for continuity of care; emergency services need persistent trails to reconstruct events; democratic institutions benefit from transparency, while individuals deserve protections against unwanted exposure.
