The fun of reading to me is constructing the world in my minds eye and turning the words on the page into a visual experience only found in my mind using imagination. This is a reason why many people get upset when a movie adaptation is made and the actor chosen for their favorite character feels very off or wrong; their mental picture of that character is totally different and it causes dissonance that our brains don’t like. For my partner this is a non issue because they never make a mental image of the person, so the movie is genuinely the first time they are “seeing” a physical representation of the character.
The human mind is genuinely amazing and fascinating and I believe that this range of human experience will be the final 20% for “AI” that might never be reproducible.
