Usually we worry that robotic automatons are taking our jobs, but this time around holograms have weaseled their way into one airport's workforce. In Paris, one major airport is piloting a test program that replaces gate workers with holographic projections that look just like the real thing — and they don't ever seem frustrated about that extra carry-on you tried to sneak on board.

When it's nearly time to bust out your boarding pass, a living, breathing boarding agent can push a button to fire up the holograms, which then do part of the work, welcoming passengers and providing information about the status of the flight. The projections, which are beamed onto a human-shaped piece of plexiglass, look and sound like the real thing. See for yourself in the video below.
