It could be just a display/HUD for your phone, sure. That might be more human for when you can't use your voice. But most of the interaction Google shows is via voice, so I'm not seeing it yet, and if it's an afterthought, then I'm guessing it won't be great.

You can control it via touch. This info is present in many reviews. Why are you dismissing something without even researching it?

As I said earlier I'm not sure how much can be controlled via touch but that is a not a big problem to solve. Google shows off voice interactions because it is more cool.
