<i>There are of course completely useless UI but for most of the UI we are talking about here it really just is a matter of learning it and most of the times making something easy to learn might mean that it&#x27;s not as powerful to use. I.e. there are no right solution just a bunch of solutions each with their various drawbacks and advantages.</i><p>That may be true to an extent, but UIs could offer a lot more support to beginners trying to find their way around than many of the current generation of mobile UIs do. I agree there is always a balancing act, but at the moment we seem to be getting the worse end on all of the scales at once, with limited functionality, limited discoverability, and limited aesthetics. And the really sad part is that this has been a step backwards from the state of the art just a few years ago, when the typical mobile UI was both more attractive and easier to use than the flat junk that Apple, Google and Microsoft seem to be obsessed with today.
