While reading about 4chan's Japanese progenitor website, it occurred to me that I know nothing about the state of rationality in the non-English-speaking world, and more specifically the non-English-speaking internet. Is there a Russian version of SIAI? A Japanese Less Wrong? What about Korean Robin Hansons and Eliezer Yudkowskys?
If we take Religion as any indication of irrationality then America should be one of the least rational countries in the world. So if there are like-minded individuals out there speaking in languages we don't know, are we doing anything to collaborate with them? Do they have their own sequences and their own HPMORs which we could be reading?
And if there are no Singularitarian, Cryonics-Supporting, Utilitarianism-Advocating websites for the majority of the human race, isn't that a huge deal? Aren't Europeans and Asians more likely to be open to rationality, if only because of their atheism? If we want Friendly-AI to be developed, should we be translating the sequences into Chinese and Hindu as quickly as possible?
Assuming you consider believing in zero gods rational... Why privilege one number out of infinitely many? On the other hand, maybe you meant agnostic.
People without the need to believe in supernatural, whether organized or not, whether called God or Communism or Dear Leader or Fair Universe, have always been a small minority, a tail of the Bell curve of belief strength. Thus I would not expect the mainstream beliefs to affect the fraction of people looking for non-mysterious answers. Of course, this model might be bad, I have not done any research in the area.
One could just as easily argue that exposing more people to EY's ideas could lead to more dangerous AI research by rogue groups, so maybe they should be kept under wraps!
Occam's razor. Deity hypotheses are both very complicated and don't offer much in the way of useful predictions.
