Except that we are all part of this "doomed civilization", and if it collapses in civil war, nuclear apocalypse or even just a gigantic economic collapse, being at poolside won't keep you fixingsafe. So we have to save it, or to fix it.

His argument is that the modern world was doomed before we where born, there is nothing really one can do to reform or save it. There can be no "have to" when there is a fairly strong possibility that nothing can be done, because incentives, biases and plain ignorance are aligned in such a way that effective positive action will bring overwhelming response against it. Anyone who thinks voting will solve anything has quite a bit of a way to go in my mind.

When civil war/nuclear apocalypse/gigantic economic collapse comes Roissy will still have a tan when it happens. The activist won't.

Now you can say that building a friendly AI is a much more efficient way of saving it/fixing it that getting involved in politics. That's something I can fully respect. But saying that you don't care or don't want to try is irresponsible.

Actually I do think it is by far the most productive course of action, and I do support that effort as much as I can. But should that in itself raise some alarm bells in our minds? Getting Friendly AI right before it is too late is such long shot by most estimates. If contributing to this is indeed the best option for maximising desirable mid term future states of the universe for an individual or small group, we should pause to think about just how little certainty and influence a person has on a system composed of 7 billion people, their machines and the natural envrionment

Because what matter is to win.

For some games the only way to win is not to play. I am quite certain the average LWer will do the world much more good if he tries to promote rational thinking and tries, as best as he can, to detached and disinvest himself both emotionally and resource-wise from daily politics and ideology.

I am not saying the tiny influence a person has on the world automatically dosen't matter if a huge payoff is at all possible. I am saying that people are over-invested into politics, far beyond the point of diminishing returns due to our brains and our society tricking us into believing we matter far more in the process of government than we actually do. Remember the opportunity cost of involvement in politics!

I partially endorse the poolside getting a tan recommendation, because I'm actually convinced that taking a swim in the pool each morning for 30 minutes rather than reading political commentary will give the world more utility, because of your improved well being and productivity in other endeavours. Its likley not the optimal use of your time, but don't let the perfect become the enemy of the good.
