Yes, perhaps that's something to do with the natural languages, where one is in pictures, and the other in text. The way we understand and express concepts. Translating one to the other must involve mental gymnastics, but they get better at it all the time.
This is a photo of the keyboard (UI) for the first (maybe second?) generation reading machine. Poor quality but, if you could look closer, you would note that none of the keys or controls are labeled. (you're blind, what value labels???)
Yet, you quickly learned where each button/control was located, even though you couldn't SEE to navigate the layout. Otherwise, use would be even more tedious than it already was!
This is the keypad from a later model of the machine:
Yet, it still reflects the initial "engineering" approach to a UI problem that likely could have benefited from more user involvement.
What annoys me is gadgets with multiple, complex hidden internal states. That is often done to minimize the number of pushbuttons, but more often done by a kutzy programmer. A computer keyboard really only needs one key.
People can be bad programmers in any language.
I have a very nice power supply that's almost unusable.

I have a couple of 300V 1A supplies very similar to that one. They work, but I agree the user interface is horrible. The internal clearance between one of the output terminals and one of the USB connector pins is only about 1mm. John
There are pretty good except for the ghastly switching spikes. The kluge helps a lot.
