Now that you really can make it on your own, tell us your ideas about the technology featured in this program.

In "Never Forget a Face," MIT student Brian Clarkson takes a trip down memory lane with Alan. Clarkson recorded every waking moment of his last hundred days with the wearable computer he calls "the turtle." Alan wondered about the privacy issues. What if someone who passes Clarkson on the street doesn't want to become a permanent part of his home movies? Clarkson acknowledges the problem, but tells Alan that social etiquette will eventually catch up with the technology. What do you think?
