I am all for space exploration and find it awe inspiring
But I think we cant colonize other planets, we can although atleast in the near future only set-up laboratories and send humans to do science up there. Ofcource Mr.Bezos would want to mine diamonds on Uranus.
What I really want to see happen is how they will avoid the Kessler Syndrome
I don't think it would be right to say "we can't do it". History is proof to the fact that humanity has always managed to do what was once considered impossible.
