I also took a while to understand what was meant, so here is my understanding of the meaning:
Assumptions: There will be a singularity in 100 years. If the proposed research is started now it will be a successful singularity, e.g. friendly AI. If the proposed research isn't started by the time of the singularity, it will be a unsuccessful (negative) singularity, but still a singularity. The probability of the successful singularity linearly decreases with the time when the research starts, from 100 percent now, to 0 percent in 100 years time.
A 1 in 80 billion chance of saving 80 billion galaxies is equivalent to definitely saving 1 galaxy, and the linearly decreasing chance of a successful singularity affecting all of them is equivalent to a linearly decreasing number being affected. 25 galaxies per second is the rate of that decrease.
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.
