But if you can extract information from it, it isn't in fact random. The definition of a random sequence is that no matter how much of it you have, there is no way even in principle to compute any information about the next item. This is why their information capacity is as high as it can get, because you can't compress them into a smaller package. But this also means that you can't in any sense parse them: you can't find any structure in them to utilize to say something about something else. They are entirely used up being themselves. All they can do, as it were, by way of communication, is to exhibit themselves and then stop.
I had better stop this conversation myself, as I am getting to the point where I have no confidence that I know what I am talking about :-)
In fact from the point of view of each
I think there is an important distinction between appearing random and actually being random. You seem here to be talking about something like a hologram (?)
a lot like an uncertainty principle, or at least Chaitin's Omega.
No, and indeed I don't know that term. I will go and find out more about it, thanks for the pointer.
