These implicit biases, which draw beliefs about emerging technology due to its full capabilities being unknown, go on to influence our perceptions of everything from smartphone apps to flight instruments used to pilot an aircraft.
Many technologies can be used for the wrong reasons. However, that does not mean we should not use them — it means we need to have an objective appreciation of their benefits and proceed with a decision accompanied by full knowledge of circumstantial facts and limitations. In fact, there's nothing inherently negative — or even particularly new — about recognising a person from their physical characteristics.

There's a downside to cars or the internet or prescription drugs, but society chooses to limit the risks through a combination of regulation and technical improvements.
