Re: Trump is thinking of the possibilities.
actually... Trump's billions devoted to a moon casino might actually MAKE IT HAPPEN!
it's nearly 2018 and we don't have a moon base. This is probably because space exploration has been hampered by politics, government budgets, and over-regulation. In the last few years, de-regulation has allowed Musk (and others) to join the game, but there are still "gummint subsidies" (in a way) that are involved.
Once PRIVATE money is driving the game, and PROFIT becomes the motivation (not getting re-elected or 'giving' money to those that give money to you), you'll see more ways in which businesses try to get you to spend your money on what they have to offer, and I have NO doubt that enough people WILL want those things in order to make them happen.
I know _I_ would. I'd love a vacation on the moon! Heinlein wrote a short story that involved tourists flying pedal-driven aircraft in a large volcanic cave on the moon. Gotta love it!
[putting on my conspiracy theory hat, I'd say "we" have been deliberately "held back" "for our own good" by some puppeteer that saw how fast we WERE advancing and wanted to put a STOP to it... while politicians THEN deliberately re-shape budgets to enhance their re-election rather than moving forward]
