Why the AI we rely on can't get privacy right (yet)

While artificial intelligence (AI) powered technologies are now commonly appearing in many digital services we interact with on a daily basis, an often neglected truth is that few companies are actually building the underlying AI technology. A good example of this is facial recognition technology, which is exceptionally complex to build and requires millions upon millions of facial images to train the machine learning models. Consider all of the facial recognition based authentication and verification components of all the different services you use. Each service did not reinvent the wheel when making facial recognition available in their service; instead, they integrated with an AI technology provider. An obvious case of this is iOS services that have integrated FaceID, for example, to quickly log into your bank account.
