I guess the main issue is the media will drum up some moral panic about undesirables using devices like this, to record clips of children or whatever.
I've often thought about a device that would catalogue my life, what I did, be intelligent enough to group events together etc, have a searchable index of time, places, people. But the ethical implications of this are just too great, and effects on society would shift in strange ways. There was an episode of Black Mirror a few years ago that explored this, in some ways it is "be careful what you wish for"
Narrative Clip (http://getnarrative.com) is pretty close to what you're talking about. The intelligence of the software isn't/wasn't there. Though you could upload to google photos and get some of that.
In the near term there's no worry about ethics. My friends and family found the Narrative Clip interesting to varying degrees but almost none of them were interested in it for themselves.
