I just saw this:
Some folks are doing video recordings to be played back on a person shaped screen sitting in the middle of an airport. It's not actually a hologram, of course, but it really looks like something out of a science fiction movie.
On one hand it's pretty cool, something I'd like to see in person. On the other hand, it's a bit creepy, given the overenthusiastic performance by the actress, with an expression that suggests something robotic or artificial.
It's interesting to me how many science fiction ideas are coming to the real world. Maybe we don't have practical flying cars yet, but it really is the future.
