This is the part that many people are missing. Decades ago I heard "the ideal UI is a search box," and I agree today even more.

I don't understand why people are still thinking that clicking on stuff will still be a desirable thing in the future.

Inputs for the ui might be me talking, or typing, or having someone else talk or type. They might also be GPS, temperature, BLE devices nearby. Or maybe a button I smash because I don't feel like re explaining something.

What happens after an input is still the best part of a UI. We like seeing/hearing/feeling things in different ways.

What you’re describing is basically a terminal. We’ve had those for a while.
