In reality the majority of owners of todays cheap cameras aren't using them to entertain you or anyone else. We are actually just snapshotting our own memories and the raw unedited result will be good enough for it's job - triggering our memory. The mainstream you think need targeting don't care, aren't sharing tedious slide shows or very much of what they take.
Good editing solutions solve a problem almost none of us has. 3D in casual photography similarly offers something few care about. To succeed it needs to have zero cost over just taking a crappy 2D snapshot.
