I think you could get overexcited about these things if you forget the human nature. The world is not going to change its ways because Silicon Valley wants so! As somebody who’s developing an AI-powered bot, I’m well aware of its limitations. Voice and text inerfaces will only be succcessful in situations where it’s natural to human to use them. Many people don’t order food or car by voice because its unnatural/hard for them and Viv is not going to change the human nature. Wake up to the reality please!
