If I am not mistaken Marty McFly went to the future in early 2013 or late 2012. And yes my lil buddy Jabbadabbado does not take into his calc that folks like Space-X are trying to make access to orbit cheaper and even a partial success steals from larger competitors who will be forced to get less expensive. "My sincere belief is that's the fundamental mistake of classic sci fi. We are sentenced to imprisonment on our home planet for the life of our species, as is any intelligent life in the universe. For all practical purposes we are utterly alone, and there is no help for us other than what we can do to create a sustainable path for the human race on our home planet by limiting our population and by limiting and maximizing the efficiency of our consumption of limited resources." True! But we limited to expansion only because of corrupt economics, and as I just pointed out certain folks are well on their way to overcoming this hurdle.
