Interesting Question...I enjoy reading a lot of sci fi literature and watching sci fi films. Often sci fi writers are described as being prophetic, and I do recall in a story, maybe Do Androids Dream of Electric Sheep (Bladerunner), the dominant language in the story which took place in San Francisco is a mixture of English, Spanish, Chinese, and some other Asian languages possibly. It's depicted somewhat in the film as you see the characters speaking some mixture of English and Asian languages. There are common known terms already for this sort of fusion of languages. Spanglish and Konglish (Korean/English) have become common terms to describe the idea.
