Ground to orbit flight for a fraction of the current cost. That’s what is likely on the horizon. Keep in mind that this is conjecture but the possibility of affordable space flight could be reached within your lifetime. (Also, sorry for the click-bait title. It’s meant to be tongue in cheek)
Remember in August of 2013 when Elon Musk introduced Hyperloop? He asked us to envision a railgun, a Concord jet, an air hocky table and a freeway having a baby. Hyperloop would solve time management and economic problems by catapulting you in a pod through a low pressure tube to your destination.
So what’s worth writing about? Rocket fuel expended to achieve orbit is least effective in the initial phases of flight. So instead mount a small rocket engine on the back of that pod, or swap the pod for the SpaceX Crew Dragon capsule and point the open end towards space.
