I disagree.

Here's a thing I'd like to do that I can't do today:

I go out for a 15 minute walk. I turn my device on. When I get back, I have a text file about my walk annotated with what I saw, landmarks, weather, perhaps an unusual car, and what I bought at the coffeeshop, all taken from the camera alone.

That's useful, doesn't exist now, but could exist in the future, using technology like this.
