Pantalaimon, avert your eyes.
According to this article, a couple of professors have come up with a new device “inspired by the Philip Pullman fantasy novels – recently turned into the hit film The Golden Compass – which include animal daemons which are physical representations of character’s souls.” They have in mind “… biometric daemons [that] could carry people’s personal details and replace pin numbers and passwords for everyday transactions, reacting to different levels of risk and becoming stressed and eventually dying if they are apart from their owner.”
According to one of the professors, Dr. Clark, “The idea of the daemon is that it is a living credit card,” he said. “It would recognise it is with you, and if you put it in your pocket, it can recognise your walk and your voice.”
And would it also know what is in my heart?
