Our interfaces have more modalities than before but they are disconnected from both physical and emotional reality. Buzzes and dings and flaps are nothing like hearing a happy shout from a friend or feeling the 'clunk' of an actual motor starter engaging.
I totally agree with OP that the 'flat' visual style is appalling. (And gray-on-gray text is an obscenity.)
I don't want my computer's interface to be overtly "emotional". I don't want it to have the same effect as "a happy shout from a friend". I want it to be unobtrusive and functional, so that I can pay attention to the message my friend recorded with their happy shout that is actually real. And I prefer my cars quiet because I want to keep my focus on the environment.
And what do you mean, disconnected from physical reality? I listed the examples where I pay with my wrist, squeeze my earbuds, draw with a pencil. I also snap photos and take videos, record with voice memos, send a pin with my location. I track AirTags, I identify plants by pointing at them, I learn constellations by aiming at them. Computing is more connected to physical reality than ever.
The two best experiences I had with touch were the the Sony WH-H900N [0] and Procreate on Ipad. The headphones had a touch surface where tap was play/pause and swipe up/down manipulate volume and swipe left/right change track. Due to the large surface, it was easy and quick to do these actions and natural.
Another good experience was shaking my phone (an Android Motorola) to turn the flash light on and off. Another great natural movement is taking my iPhone and transfer the playing music to an Homepod by tapping on the two together.
For almost everything else I loathe touch devices. While older ones may be clunky visually, they are far more ergonomic. Yes, my phone can do a lot of stuff, but the whole process for a specific one is always clunky and companies go out of their ways to block you from altering the UX.
