> How long before a significant amount of search is simply asking some device a question and being told the answer?

Probably never. People read way faster than listen and in a productivity obsessed world this matters a lot. People also don't want others to hear what they are searching for. And these things are part of human nature, not something to get used to.

I can see people doing voice-typing on mobile when they are in private, because mobile is super awkward to type on. But that's about it.
