On the day when Apple are supposed to be launching a new iPhone with facial scanning capability, the Guardian has delightfully timed a piece warning of the dangers of the technology. Its functions potentially extend to predicting sexual orientation, political disposition, or nefarious intent. What secrets can remain in the face of this extraordinary power! Indeed, it’s two years ago since I heard Martin Geddes talking about people continuing to wear face masks in Hong Kong not because of the smog, but to avoid facial scanning technologies deployed by an overbearing security apparatus. There’s no hiding from the data, no forgetting.
