For the record, I came up with this thought, about computers and software being optimized for text, by realizing I learned the best by reading information presented as a combination of text and media (e.g., a textbook with diagrams), but when I communicate with a computer, I always just use text, why? Well, making media with a computer is a huge PITA, I'm assuming because you program the computer itself with text, so its entire interface seems optimized for that. (This is particularly interesting looking in contrast to smartphones and tablets, which are entirely not optimized for text.)
