With the recent advances in 3D printing and robotics, there will be a time when traveling to conferences to meet people in person will work like this:
You send a 3D scan of your head and hands to a 3D printing service plus a set of clothes via normal mail. When the clothes arrive and the face has been printed, both will be dressed on an android frame.
The androids will then meet “in person” while you can safely stay at home.
