Another comment, this post has some great bits in it, stuff I've really empathized with at one time or another, but I think your conclusions are wrong. I really do. It reminds me of the post in the "what do you want to be when you grow up" thread the other day, with the human condition observation stuff -- and crap I'm incoherent -- but basically you're right about everything, especially:

It seems like everyone else either knows this as a fact of life, or just doesn't care. As if they don't care about the whole reason they can observe in the first place. Just watching people makes me sad. What do they do? Facebook. Reddit. Hubski. Youtube. Hell, maybe they'll even work or go to class. Just mindlessly. Without care. over and over. For all of time. You bring it up to them, and they'll have one of three actions. The first is be outraged and ignore you. The second is be interested, and think about it for a little, and ultimately dismiss it. The third becomes like you. Curious and are unable to come to a conclusion.

It's hard to be motivated and happy when you realize you are stuck. I guess some people would take it as a sign that they can do whatever, but you hardly see those people. And they don't realize what "forever" is. Or perhaps they do and don't care.

But how can one not care about their entire existence?

BUT -- why does this depress you? Why do you feel stuck? Another case of me agreeing with someone on hubski but drawing completely different conclusions from that consensus. Life is fascinating and incredible and if you're even bothering to read about quantum suicide that means you grasp some of its most beautiful facets. I don't want to know the answer, life shouldn't give up its secrets so easily. I fucking love that we as a species have no idea why we're here, or if there is a why, that maybe we're here for no reason but chance. Or maybe we have a grand purpose, but you I and will be long dead before it's realized. That too is bittersweet, but sweet all the same.

I don't know. Why is an amazing question, it's a special word -- it's the word that makes homo sapiens what it is. But answers don't need to emerge in order for great people to continue asking the hard questions. That's why we are where we are today, and why we'll be where we are in the future. Whichever of the many worlds that may be.

Keep making posts like this. I should really stop getting on hubski while I'm drunk, but I enjoyed thinking about this.
