I just watched a discussion on C-Span about Mars

53. Some people only want the "right part" of humanity to survive

and the "right part" usually bears an uncanny resemblance to themselves.

The problem with sectarianism and tribalism in a lot of the world is that it has worked very well for a very long time, at least for males. I'm hoping that once the borders are withdrawn and people experience stability without a dictator and his secret police, all the violent bullshit will start to decrease.

We nurses are used to having to check our prejudices, politics, and religion at the door. Civilians have rarely experienced that to the same level we have, and that makes a difference.

I would hope that human exploration and terraforming Mars would be delayed for a very long time due to insurmountable obstacles, like designing a ship that could repel micrometeorites traveling in at Mach 20 and more. Maybe we'll grow up as a species by the time that happens. We'll have to grow up a lot farther than we have just to tackle such problems.
