But will you agree that as ISO increases there is no way to access that light so no one cares?

I was only pointing out "The ISO setting doesn't change the amount of light the sensor collects"

I'm sure I said that above,

You started with the opposite though

My first post said:
"It only helps if you can reduce the ISO, which changes how much light you collect to give a correct exposure."
Which is how the camera exposure system works.

My second post said:
"I'd disagree about the point here - what ISO changes is the upper limit to how much light you can collect, as it amplifies the signal coming from the pixel and so will clip at a lower level."
Which is how it works.

Third one:
"I think my view is the more useful one here, as while ISO doesn't change the amount of light the sensor collects it does change whether you can use that for an image. Every time you crank the ISO up another part of the sensor's capacity becomes hidden and you can't measure it and can't use it to make an image."
