With mea­sure­ment comes the pow­er to cat­e­go­rize and con­trol. These are tech­nolo­gies that enable us to be judged at a dis­tance, to be iden­ti­fied as a threat or a sales oppor­tu­ni­ty just by the way we look. Facial recog­ni­tion takes this fur­ther. Not only can we be reduced to a set of externally-verifiable mea­sure­ments, but the­se mea­sure­ments are assumed to some­how con­sti­tute our iden­ti­ty.
