It is difficult to losslessly compress something that has already been losslessly compressed, because its entropy/bit will be very high.
De-compressing something you already had losslessly encoded feels like learning or discovery, depending on whether it is externally induced.
Like, if you know the statement of a difficult math problem, then you know enough information to pin down the answer, but you do not know the answer. If I tell you the answer, you will feel like you just learned something. And you did, in some senses of the word, learn something.
wouldn’t everything physical include, say, your complete brain state now and what your complete brain state would be if you saw something red?
and wouldn’t it be impossible for you to hold that info in your brain?
Not if you could losslessly encode it enough and also work directly with such encodings.
