It's fascinating how much AI struggles to mimic signs and text. With as much as we enter text into computers, my instinct was to think this should be really easy for computers, but they don't actually receive and process the abstraction of writing like we do, do they?
We use shapes to indicate sounds and sequences to make words, but the computer is ultimately just getting 1 or 0, on or off. It doesn't seem that it does have the associations we use intuitively because of how humans interact with language.
