I found out why: theguardian.com/science/2012/aug/30/… Sorry for my bad wording. English is not my native ; )

@GregPetersen, I would appreciate someone helping me rephrase that way.

comment Is there really a direction of time?
If time is a quantity we use to compare events as you said, isn't it already subjective in some sense? Anyway, I think the most we can say is something like "it is coherent to say time is subjective/objective in this theory/framework about how the universe and mind work".

comment Is there really a direction of time?
I agree that physical laws say little about time. I tend to think direction of time is like color, it stubbornly looked like part of reality until we find out it's just the way we are built to perceive the world.

But consider a Demon with a very large memory. It can make the engines do a lot of work (i.e., run many cycles) before there must be any erasure. What happens to the entropy of this system?

comment How can the microstates be measured with zero energy expenditure?
Thank you. I found your argument very clear. Just one point: do you agree with this: Upon each erasure the entropy of the Demon (if isolated from environment) must increase by at least 1 bit (Landauer's principle), although this increase may be "subtly" dispersed out among the Demon's components as you pointed out. If so, then the total entropy of the system is already non-decreasing upon each erasure and there's no paradox anymore. Why wait for repeated erasure and the Berkenstein Bound?

comment Why can the entropy of an isolated system increase?
Entropy is ultimately a measure of our ignorance of the microstates of the system.
