I agree, but maybe it is not the norm for design folks?

I'm thinking of the movie "Her" where the ai assistant was only ever a voice. And siri, and grok in a tesla, etc. I think we can do non-visual personas.

I don't know, maybe corporate design folks think in trademarks and logos and this is just part of that?

(or what about deaf people? Do they need text, or something amenable to lip reading?)
