So, the conclusion of this article is, if there is intelligent life out there and it is anything like us, we can be absolutely sure we will never hear from them at all - they will be way too self-absorbed, ego-centric, and taken up with trivialities to ever bother reaching out. As to one of the commenters who asked "Is this a photography site or a 'cheap' philosophical blog?". Assuming that (A) photography is an art form, and (B) Art is about the world we live in, so that (C) photography tries to say something about the world we live in - when I look at most photo-sharing sites, blogs and forums about photography, it would seem to me that photography mostly IS a form of rather cheap philosophy.
