Consider the plumbing of ancient Rome, or the engineering of the Andalusian Moors. And a lot of more peoples, just like them.
Throughout the ages.
Each of them presumably thought of themselves as the height of civilisation. Just as we do.
How far ahead of them are we, in reality?
Should a single nation foot the bill for research in a propulsion technology that can take us to the stars?
And – when we get there. Will we have changed? Or will we still be bickering narrow minded humans thinking ourselves superior to all and everyone, including ourselves?
At the moment, I’m not very hopeful.
