"I am a pessimist by nature. Many people can only keep on fighting when they expect to win. I'm not like that, I always expect to lose. I fight anyway, and sometimes I win."
-- Richard Stallman
Fuck hope and optimism. I am gonna go out and fight no matter what. Doing nothing makes me sick.
For me it was far more "we're fucked" than inspiring call to action. Haven't given up trying yet, though I am not at all hopeful now.
I can imagine this being true.
If a meteor is going to destroy Earth you probably aren't spending your last few days doing the dishes and sweeping the floors. You're only doing that if there's a > 50% chance that we'll be able to divert it.
And better than "being optimistic" is rapidly developing the technology and passing the law to make it realistic.
Not everyone sizes up the issues.
