I mostly agree but think you underestimate the “contexts where we actually want visual interaction” - a screen is not just for consuming visual media. It might be that all input is spoken, but output will always need a screen, because spoken word is just incredibly low bandwidth compared to a good text layout. Imagine an order confirmation page for a complex food delivery order, where you’ve made a couple of item modifications and you’re using a promotional deal for a discount on the total price. You can take in all that info in 2 seconds if it’s nicely laid out on a screen. Compare that to having to listen carefully to a voice reciting it all for you. And same goes for things like just browsing other songs by the same artist you’re listening to. Text on a screen, with good typographical layout for fast mental processing, will still be the best output format for many use cases.
