Dawn of a new era.

I like to compare present day rocketry to the early days of automobile manufacturing. Look back at how many big businesses came into being because of the automobile. Oil companies, tire manufacturers, auto parts companies, and dozens of others just for starters. The travel business, new type of hotels and restaurants. Not to mention the trucking industry and everything it spurred. The entire road and highway system.
So, now I'm trying to imagine what future global businesses will arise from our venture into space. I am fascinated by this unknown future and where the beginnings of today will lead in one hundred years, 500 years 1,000's of years. Science fiction is rather rapidly becoming science fact.
We went building an airplane that flew several hundred feet, not far off the ground, to landing a manned rocket on the moon in about 60 years! That's incredible to say the least.
I hope all of you young entrepreneurs out are realizing the potential right in front of you.
