I agree, but don't throw the baby out. One of the most useful uses of voice I've found is using a Fire stick with Alexa. Just press the mic button on the remote and say a actor/movie/tv series and it presents everything it finds from all your subscriptions. It's rare it doesn't understand and as a Glaswegian that's impressive.
This is true for me, on Roku. Considering the context, that's far from a platform, it's not even an interface. It's just an alternative input to the physical tv remote interface. If I were to simply re-task a tablet or old phone as my TV remote (easy to do with Roku), I'd stop using voice, and get much more out of the second screen.
