Perhaps. It depends of your definition of "OM", and of your
Let me tell you the "Lobian's answer": if I have a successor OM then
have a successor OM which has no successor OM.
I don't understand this statement, for me, every OM has a successor,
every integer has. How could it be that an OM can't have a successor ?
But I'm firmly convinced that the set of visual OM (I mean by visual,
something an observer like a human can see) is finite.
OK. But you could take the whole perception field. Our skin is finite
Etc. Oh Stathis take even the state of each neurons ...
Anyway, by the comp hyp I presuppose at once there is such finite

2) assume that the observer can see only at a certain resolution/level

Then, I can digitalize every image that I (assuming I'm an observer ;)
Now, I'll take an arbitrary image resolution far upper than I details

see less than 200000 colors, just for the argument). Then the limit
eyes to see individual images in a movie is approximately 40hz, so for
argument I will say that I need at least 100 frames by second (higher
what we can perceive).
Now how much bits do I need to encode one hour of visual events ?
It's simply 100000x100000x4x100x3600.
So the needed number of bits to encode one hour of visual events at a
resolution far higher than what we can perceive is finite... It's the
you replace one hour by the length of a lifetime (+/- 80 years). So
we are immortal, at a given time in the far away future, the visual
Not really because you assume our eyes are bounded. Any finite machine
running forever recurs but not infinite or universal one.
