I have a theory that corporations make new UIs to entertain people through them. First, to create the feeling that something is happening, and second, to increase screen time.

Old interfaces were far more practical for getting work done, and therefore obviously boring.

For me, as someone who is supposed to use technology as a tool and not as a source of amusement, the new interfaces of the major OSes feel unacceptable. But the other billion people chatting and scrolling are the real consumers, not me — and as a result, we now have the interfaces we have.

Not really a theory.

Software makers treat UIs the way auto makers treat paint and body styling.
