>visual systems fed from a constrained input domain lose the ability to meaningfully represent real-world input.

Seems to imply that looking at a computer monitor for too much of your life means you won't be able to see the real world, or not "see it right", whatever that means.

The only example of that I've seen is some people (kids, presumably) commenting on the Nvidia RTX demo videos that the non-raytraced versions, which lack real world lighting dynamics, look "better" than the raytraced ones, which were, to me at least, obviously closer to physically realistic, representative images. Now, whether they were saying that because their eyes have literally programmed themselves for cheaply rendered video game worlds, or because they didn't want to face spending the asking price of the RTX hardware, is up to the reader.
