the problem isn't necessarily that NASA is too risk-averse when it comes to human lives, it's society at large.

I couldn't agree more. I'm continually saddened that the traditional salutation to a guest leaving your home, for example, is "have a safe trip". In my dream world, people would wish each other a "a rich life of fulfilling experiences".

We shouldn't be trying to wrap ourselves into cocoons, setting a goal of simply surviving for the longest possible time. The length of the life shouldn't be paramount: it should be the area under the curve: how much did we experience, to what extent were we able to pursue our dreams?
