"It takes four hundred thirty people to man a starship. With this, you don't need anyone. One machine can do all those things they send men out to do now. Men no longer need die in space, or on some alien world. Men can live, and go on to achieve greater things than fact-finding and dying for galactic space, which is neither ours to give or to take. You can't understand. We don't want to destroy life, we want to save it!" -- Blacula

I say this jokingly, but I really did drink the Kool Aide, and I think it's just Kool Aide without any additional harmful ingredients. I'm seriously all for us at least striving to live a completely hedonistic lifestyle, where we never toil because our robots slaves do everything tedious for us.
I want to die in an Orion whorehouse, looking like a character from WALL-E. Only in my final moments do I want to learn the awful truth, when one of the green-skinned ladies' faceplate falls off, revealing a robot.
Ok, maybe it wasn't pure Kool Aide.
