Big brother potential aside, I could imagine a future in which everyone wears a body camera everywhere. A digital record of your entire life. Given increasingly good AI extraction, you can then have searchable transcripts of your conversations, query your life for the last time you saw movie X (interesting IP questions here), re-experience moments with grandma, whatever. There was a Black Mirror episode incorporating this concept.

If you find such a concept interesting, I would recommend the movie Final Cut (2004) with Robin Williams. Not a particularly good movie but it does have this as an interesting premise.
