Text and spoken language are extremely linear. Visual and sign language are extremely spatial, like in Arrival / Story of Your Life. ASL is not signed one word at a time. Automated translation is difficult, because ASL is not Signed English, it doesn't translate word for word. Deaf people can (and usually do) learn to read and write the local language.
