This is the theory. And I don't think you're wrong at all in analyzing the motives/endgame here. But there are reasons texting arose as a preferred alternative to voice. Audio interfaces will win in cars, possibly homes and other well-defined private spaces. But text is ubiquitous and visual interfaces are so much faster, as audio is limited by its linear dimension. No doubt, voice control will be a huge market, but I think the idea is more alluring than the reality will prove.
