Regardless of how good voice interfaces get, the inherent limitations and restrictions that come with it means that we'll all still be doing a whole lot of typing until/unless a new and better input method is invented.
Or maybe it would be a combination of internal voice and ephemeral voiceless conception, or maybe thinking with "intent". Whatever it would be, it would certainly take effort to some degree.
Maybe AI could filter that nonsense out based on contextual clues, but not the AI we have so far, hence I think the monologue would need that second voice. 'Remember Nikki, think all code things and only code things in scottish... Aye, I shall.... och, bollocks!'
What sort of limitations/restrictions do you see with it, beyond accuracy (which is continually improving)?
Such as... voice is really awful at communicating with great precision and exactness. It can certainly be used for that, but it rapidly becomes tedious and very time-consuming. Using a keyboard is faster, more accurate, and more convenient for that sort of thing.
