Why do you say that? Have you ever taken a photo with the lens cap on?
I just looked at my digital camera in my phone and blocked the lens
with my hand and there is no noise or snow whatsoever. If I unplug the
monitor from my computer but leave it powered on - no snow.

Phosphene is nothing more than a name. Calling them hallucinations is
a loaded term. They are visual qualia, to me pretty obviously related
to the physical neurology of the optical system and not to any
computational interpretation software. You all can disagree, but I
know that what I see seems like analog 'respiration', not digital

That should be easy enough to test. The point though, is that it has
no business leaking into our visual software. No computer has
comparable thermal noise that leaks into the software, does it? You
can get RF interference, sure, but why would a program tuned precisely
to represent some things and not others include unfiltered noise in
it's representation? I know it's not evidence that contradicts comp,
but it's not supportive of it at all.

We shouldn't ever see raw unfiltered inputs, that's why the phosphene
doesn't make sense as a filtered process.

Noise should either be unavoidable or absent, not present if we pay
attention to the front of our visual field and absent if we visualize
darkness. The fact that there is a difference for human vision behind
closed eyes and within the mind's eye would need to be explained.

I don't know what people think I don't understand about COMP is. It
makes perfect sense to me, it just happens to be exactly wrong in the
real world. In a theoretical world, COMP is the way to go, definitely.
