That's what I thought until i witness people in my family using: 1. Google voice and 2. Alexa (and raving about it)

I think tech people just find typing away much faster and voice interface kinda annoying, but a lot of more 'average type of users' really like the voice interface better.

I wouldn't have predicted, but voice is here to stay and it has long legs. It seems that casual home use, and in car (where the next battle will be) are the best uses of it, and not mobile/while out
