Alex Kipman : A futuristic vision of the age of holograms

Alex Kipman at TED2016
A futuristic vision of the age of holograms  (transcript)
Summary
I thought that this talk was unlikely and a little bit tricky.
The speaker challenged showing us the Holograms that he's seeing by wearing HoloLens on the stage. Its real-life size hologram said that he is in three places. He’s standing in a room across the street, while he's standing on this stage with audiences, and while he’s standing on Mars. It's a hundred million miles away. And then, he said also that people can explore on Mars from a seat behind screen and keyboard now. However, unfortunately, we don't have touch and smell, but in the near future, we will feel the temperature of a virtual object and we might shake hands with holograms.
I imagined. Now, Skype is two dimensional. On the screen, we can see each face. Next generation, it will be three dimensional. Through the screen, we can sit next to a person who is in the opposite side of the screen. Your virtual can move my stuff though you can't bring them. Hahaha. That's amazing.
