> The cars don't have to increase ISO to get detail, that's for human eyes. Increasing ISO only works because we can't see details in shadows, but computers don't have that limitation. A neural network wouldn't have to add 100 to each pixel to make out detail, like a human would.

I'm not an expert on this stuff but I think you're misunderstanding or mixing up the ISO value with exposure compensation. The ISO value corresponds to the sensor's sensitivity, and even RAW photos (which are more or less dumps of the raw sensor data) are captured with specific ISO values, and look different at different ISOs.




Yes, the ISO is the amplifier gain, essentially.
