I think the UI is cool but sending pictures around doesn't sound "amazing" to me. Besides the fact that you could have still traded pictures via the web without Facebook, a self-driving car AI is on the fringe and can be applied to society in some pretty cool (at least to me) ways that can still make your life easier even though you live in the city.(better trains for one)

Maybe I'm just starting to get old, and the idea of certain elements from all those cheesy movies about the future I watched as a young kid coming true just isn't as "cool" as it used to be.
