> Isn’t its voice the ui? It should respond using the same context of the request. Voice and natural language.

Yeah it’s an interesting idea, but visuals are required sometimes. Even the simple task of “List the highest rated Mexican restaurants near me” works perfectly well enough with old crappy Siri. You’ll get a list of the highest rated Mexican restaurants near you. But as soon as you open the first restaurant, Siri closes and the list is gone. You can’t view the second restaurant. To get the list back you need to ask Siri again.

There’s no world in which that user experience makes a viable product. It’s a completely broken user experience no matter how smart the Gemini model is.
