>It's only very recently that living beings on this world have learned to read and write, it's not normal. It's normal to communicate through sound. It's normal for humans to communicate via sight and sound combined. That being said, we invest a lot of calories and brain power into vision. It's our primary mode of interacting with the planet. This is what we have evolved to rely on. I think, therefore, you're wrong. We rely heavily on eyesight, naturally. It's why our eyes are focused on the front, allowing precise binocular vision, whereas our ears are on the side, allowing for broader coverage, but less specific information received. Reading and writing (or at least some form of image communication) is probably more natural for communicating ideas than talking, for humans. Even if you are still trying to average us out across other life on earth (which doesn't really make a bit of sense), I think vision is the way to go. Colors and visual attractants and other visual forms of communication are common even in plants, as well as animals.
