There were many commenters who did not bother to look up what the B-theory of Time is:

B-theorists maintain that the fact that we know much less about the future simply reflects an epistemological difference between the future and the past: the future is no less real than the past; we just know less about it. -- Wikipedia

I think it is good to learn this phrase, because many LWers have strong opinions about this idea without knowing its proper name in philosophy. Personally, I very strongly feel that B-theory is a legitimate and extremely fruitful way of looking at the world. I don't really care whether it is the only proper way of looking at it.
