If you haven't seen it, S01E03 of Black Mirror, The Entire History of You, deals exactly with what PG describes at the end of this post: technology that lets you review and relive your past. It's very much worth watching, and was recently added to Netflix's library:
I just watched the whole series, and I wanted to go ahead and recommend that everyone watch more than that single episode (although I think it's one of the strongest). It's only 6 episodes total (each season has 3 episodes).
I think this audience would especially like the series:
'Black Mirror is a British television anthology series created by Charlie Brooker that shows the dark side of life and technology. Brooker noted, "each episode has a different cast, a different setting, even a different reality. But they're all about the way we live now – and the way we might be living in 10 minutes time if we're clumsy."'
Without seeing your comment I made the same recommendation to one of my lead devs a few minutes ago with the same segue, having also recommended this article.
