What makes you think that's relevant to the discussion here? The person I replied to was under the incorrect assumption that someone in possession of a phone could extract stored fingerprint images, which is not true of any well-designed biometric system.
If you do a little bit of reading about the topic, too, note how well-designed biometric systems require more than a simple fingerprint or photograph — e.g. Apple's FaceID has liveness checks for eye motion and uses a 3D scan. None of these are impossible for a well-resourced attacker but that's true of the alternatives as well. This is why you need to think in terms of threat models — e.g. the attacker who can get a high-resolution 3d scan of your face can also watch you type your passcode in so the latter isn't more secure in practice.
