Just how much are friends and family expected to attend to someone whose mind is in decline? My grandfather had Alzheimer's. We attended to him more and more as he got worse and worse. But one day, he went down to the basement while grandma was napping, and was doing something that involved a chunk of wood and a piece of pipe in a vise, heating it with a torch while beating on it with a hammer. Luckily, it just set off the smoke alarms and the fire department came. He could have burned the house down with him and grandma in it. That's what happens when you leave someone with Alzheimer's unsupervised for a few minutes. If software can help when they aren't being actively supervised, I'm all for it.
