I think your pooh-pooh'ing such infantile and amateurish efforts as there is silly when the reasoning is entirely bogus.
I hope I am not "pooh-pooh'ing". There do seem to be a number of points on which I disagree. I feel a bit as though I am up against a propaganda machine - or a reality distortion field. Part of my response is to point out that the other side of the argument has vested interests in promoting a particular world view - and so its views on the topic should be taken with multiple pinches of salt.
Why don't you refocus your criticism on the more legitimate weakness of existential risks: that is highly likely to be irrelevant (either futile or unnecessary), since by its own prediction, the relevant risks are highly complex and hard to mitigate against, and people in general are highly unlikely to either understand the issues or cooperate on them.
I am not sure I understand fully - but I think the short answer is because I don't agree with that. What risks there are, we can collectively do things about. I appreciate that it isn't easy to know what to do, and am generally supportive and sympathetic towards efforts to figure that out.
Probably my top recommendation on that front so far is corporate reputation systems. We have these huge, powerful creatures lumbering around on the planet, and governments provide little infrastructure for tracking their bad deeds. Reviews and complaints scattered around the internet is just not good enough. If there's much chance of corporation-originated intelligent machines, reputation-induced cooperation would help encourage these entities to be good and do good.
If our idea of an ethical corporation is one whose motto is "don't be evil", then that seems to be a pretty low standard. We surely want our corporations to aim higher than that.
One important aspect of corporate reputation is what it's like to work there-- and this is important on the department level and smaller level.
Abusive work environments cause a tremendous amount of misery, and there's no reliable method of finding out whether a job is likely to land you in one.
This problem is made worse if leaving a job makes an potential employee seem less reliable.
Another aspect of a universal reputation system is that there needs to be some method of updating and verification. Credit agencies are especially notable for being sloppy.
Ideally, I'd like to save the world. One way to do that involves contributing academic research, which raises the question of what's the most effective way of doing that.
The traditional wisdom says if you want to do research, you should get a job in a university. But for the most part the system seems to be set up so that you first spend a long time working for someone else and research their ideas, after which you can lead your own group, but then most of your time will be spent on applying for grants and other administrative trivia rather than actually researching the interesting stuff. Also, in Finland at least, all professors need to also spend time doing teaching, so that's another time sink.
I suspect I would have more time to actually dedicate on research, and I could get doing it quicker, if I took a part-time job and did the research in my spare time. E.g. the recommended rates for a freelance journalist in Finland would allow me to spend a week each month doing work and three weeks doing research, of course assuming that I can pull off the freelance journalism part.
What (dis)advantages does this have compared to the traditional model?

EDIT: Note that while I certainly do appreciate comments specific to my situation, I posted this over at LW and not Discussion because I was hoping the discussion would also be useful for others who might be considering an academic path. So feel free to also provide commentary that's US-specific, say.
