Thanks for the thoughtful response. Definitely some good points in here. If I had to bet, I’d bet on the (somewhat near-term) future being a combination of voice and screen. As silly as it may be to point to a movie as what is likely to happen, I could see the world of Her becoming more of a norm. Combination of hushed-tone voice and screen when you can’t talk or need to display something (or take a picture, etc).
Remember, 10 years ago it would have seemed really odd to have everyone in public with their necks craned looking at a slab of glass in their hands too. Socially awkward. Yet I look around the cafe I’m in right now, and 75% of the people are doing just that. I imagine talking to devices will happen more slowly, but I still think it will happen thanks in large part to the Echo and similar devices, as noted.
