One of the more interesting ideas to advance travel would be to erect tubes within which a capsule would travel at about 700 mph. This is like you put documents in a tube at a drive up window at a bank or they use tubes to transport documents in buildings. If you could enter of module inside a tube, vacuum becomes the energy cutting even air travel in half between major cities.

High definition 3D holographic video projection systems allow a spectacular life-size 3-dimensional moving holographic illusion to appear within a live, staged setting. This is allowing international meetings that are truly amazing and can eliminate travel.
There is a future if we can just reform the monetary system and eliminate professional politicians while restricting bureaucratic growth that always eliminates human rights.
