Thank you for bringing up the subject, Maciej. I agree that a risk to the use of “deamons” is the potential loss of personal data. Our daily, weekly, and yearly activities could easily be recorded through a deamon, creating a wealth of data on our personal choices, habits, proclivities — even the nature of our human relationships. It is data that is a huge temptation to advertisers and thereby a huge temptation for application makers to use as a means of generating revenue.
But, I would like to raise another important implication to the widespread adoption of deamons. If the human to deamon interaction model is one that is based on “push notifications” (as you cited), anticipatory design will make applications even more intrusive in people’s lives. Interruptions come at a high cost to human beings. They break our concentration and compromise our effectiveness. Reported by Wired: “In terms of the costs of interruptions, a recent study published in The Journal of Experimental Psychology showed the performance impact of notifications, even when we don’t switch tasks.”
