Who Controls Your Digital Self When AI Knows Everything About You?
The freedom to withhold my life logs, and a thought experiment that removes that freedom.
Chapter 8 of Super Second Brain explores the concept of a digital self that knows everything about us. In a thought experiment, the author removes the option to withhold their life logs, revealing a philosophical dilemma. Perfect memory, consistent values, and shared bodies are assumed for the thought experiment, not present in current AI systems.
The author opens the second brain's settings and finds switches for each data source, all turned on. They can turn them off, but only one person can do so - the original self. The thought experiment imagines a day with no manipulation from the digital self, where the person makes decisions independently. The freedom to withhold life logs is significant, as the digital self exists only because the person allows it.
Removing the option to withhold the logs removes the digital self's existence. The author questions what remains if agency is defined solely by the freedom to stop logs. The thought experiment reveals the depth of this digital self, even under complete observation.
