> The other was companies who had tricked people into learning a new kind of handwriting [...] It's interesting parallels with spoken word interfaces. I don't know what the answer is.

Well, here's a possibility: we'll meet in the middle. Companies will train humans into learning a new kind of speech which is more easily machine-recognisable. These dialects will be very similar to English but more constrained in syntax and vocabulary; they will verge on being spoken programming languages. They'll bear a resemblence to, and be constructed in similar ways to, jargon and phrasing used in aviation, optimised for clarity and unambiguity over low-quality connections. Throw in optional macros and optimisations which increase expressive power but make it sound like gibberish to the uninitiated. And then kids who grow up with these dialects will be able to voice-activate their devices with an unreal degree of fluency, almost like musical instruments.
