This is clearly the worst crowd possible, except maybe people with speech disabilities, to ask this question. Just look at how many people don't like it.
I really can't make myself talk to a machine. I even abhor the phone answering services that insist that I speak instead of punching numbers. I my household the only person that interacts with the Echo/Alexa is our 3 year-old daughter. She finds it funny.
On the other hand, the voice assistant devices are selling like crazy, so people are interested in them.
