I think I agree with this, that consciousness is created by the
information associated with a brain state, however I think two things
The first is that I don't think there is enough information within a
single Plank time or other snapshot of the brain to constitute
consciousness. As you mention below, under the view of block time,
the brain, and all other things are four-dimensional objects.
Therefore the total information composing a moment of conscious may be
spread across some non-zero segment of time.
The second problem is immediately related to the first. Lets assume
that there is consciousness within a 10 second time period, so we make
a recording of someone's brain states across 10 seconds and store it
in some suitable binary file. The question is: Are there any logical
connections between successive states when stored in this file? I
would think not.
When the brain state is embedded in block time, the laws of physics
serve as a suitable interpreter which connect the information spread
out over four-dimensions, but without computer software running the
stored brain state, there is no interpreter for the information when
it is just sitting on the disk. I think this is the reason some of us
feel a need to have information computed as opposed to it simply
