This is really cool, but personally I think I'd have some reservations about trying it myself. It reminds me a little bit of Our Town, a play that I read in high school. One of the characters dies and has the ability to relive various moments of her life. However, over time she becomes very sad because she can't actually interact with any of the people that she knew and loved; she can see them, but they can't see her, nor can she talk to them. But maybe I'm making this new tech into something more dramatic than it actually is, haha. Great article, Ben!
