The Last Private Thought
Every action, inferred. Every intention, predicted.
Privacy used to be about controlling data you actively shared. In the AI era it is about controlling what can be inferred from the data you cannot help producing. Your gait, your typing rhythm, the ambient sound of your home — all of it is signal.
Inference beats collection
Even anonymised data can be re-identified with enough correlated signals. Traditional data-protection law was written for a world that no longer exists.
The chilling effect
People behave differently when they know they are watched. A society under constant inferential surveillance is a less creative, less honest, less free society — even if nobody is punished for anything.
Private compute
On-device models, federated learning, and confidential computing give us tools to keep intelligence close to the person it serves. Whether they get adopted depends on regulation and demand.
Questions worth arguing about
- ◆Should certain inferences about you be illegal, even from data you shared?
- ◆Do you own the model an AI trained on your behaviour?
- ◆Can you consent to something you cannot understand?
