My argument is that voice isn't all that useful in general and that if Apple creates a much higher quality product than Echo, for example, that people will want it because it's a very nice speaker that looks really cool and can play music, give the weather, and set a timer by voice, which covers the majority of use cases. In other words, a voice platform that works 10x better than another may only be slightly more useful to the average consumer while if the actual speaker is 10x better, it might be 10x more compelling.
