Travelling - Is it possible on communication lines?

Tweet

The necessity is the mother of invention. This is true and people are thinking to transfer or transmit themselves through the common communication lines, whether wireless or wired form. If we think deep, we are doing this in some way. We can attend any meeting using video conference million miles away, though we are not present there but people can see and talk to us and they don’t feel our absence. Obviously we are present there virtually. I think in future this would also be possible to travel physically as what we have today, we did not even imagined a century ago. what are your views on this.
