The underlying premise that humans MUST be THERE when in actuality they are HERE has not been proven. Why does anyone have to travel at great speeds, in order to accomplish anything in this day and age of instant digital distant representation? Do you need to be there, in situ or in proxy? Could you not just conduct business via the net? Could you not just hire a simulacrum to perform your activity in your stead? And if you just bloody well HAVE to be there, then, well, you should plan to be there no? The whole StarTrek transporter need has never really been questioned. Sure StarTrek used it to get from planet to low orbit. But humans would only use it to get from SFO to LAX. That must surely register as a lame use of technology.
