I think you are being downvoted because your question "What if humanity is not secure?" is way too vague to be meaningful and sounds like it is intended as rhetorical applause lights.
That would be a rather silly reason to downvote, considering where the question comes from:
What if, as Yudkowsky states, 'Humans are not secure'?
Even if you think that it's an applause light, your criticism should probably be directed at the original author.
Currently only one teaser trailer and some info is set up on the site. Watch it. Awesome! Right?

EY's quoted in the trailer too. I guess this is a good thing. No such thing as bad publicity. :)
