interesting topic, but we have not reached the end of innovation in fact we are just starting. what you guys are talking about is meta physics or fringe science , in fact many of theses things are possible , are brain have just not evolved yet to that stage, science is also evolving and evolving very fast, look at one field which is cellular tech over the last 5 years it has leaped froged so much that it is now becoming hard to keep up with it, another interesting and already in process is 3d printing , this thing will change the very way we live !! teleportation and time travel are very tricky questions and not someone without a real understanding of the subject can answer them , but from reading on topic from respected scientists they look very much possible. 3d holographic image meetings like one poster has suggested on last page have alaredy been developed and being worked upon. many new tech are ready , an have been ready for some time infact years but the problem which any tech faces when it comes into market is that it replaces the old one. as did cars with horse carriages etc.. , the industries and corporations behind power and energy the 2 things every human depends on have been blocking alternative means of power, or even free power and fuel, look into a docu called 'who killed the electric car' it answers it a lot questions. same goes for power ppl as late early 20th century were close on giving free or cheap power ' ref to Nikola Tesla works and still pending works in cold fusion. so yes we will see changes , humans too evolve but not anytime soon, one part of history has to die before another begins.
