| There's two problems. Many UIs today are objectively bad and unintuitive (like the Gmail example in the article). UIs should always strive to eliminate the "don't know what you don't know" quadrant: common sense should be enough to navigate the system safely. Perfect examples are the Gmail example in the article, or the "hanging up the phone doesn't hang up the phone" problem of landlines[0] where you can do "everything right" and still get scammed. The judgment metric here is whether a decently intelligent people could fall victims to these; they can, so they're objectively bad UIs. They violate common sense. Then there's another group, that severely struggles with computing abstractions. (These can be perfectly smart people in other areas). They can have slightly degraded motor skills and end up swiping or tapping inadvertently and getting lost. The kind of people that thinks a locked phone is "turned off". That get confused when Control Center or Notification Center show up, because the swipe was inadvertent and they don't understand the abstraction ("where did my video go?"). It is utterly impossible to design the same UI for this group of people and for everyone else. For them, you'd ideally permanently dedicate a fifth of the screen to a never-changing menu, with common operations (copy, paste, switch app, see notifications, check email, find app). For most people, menu bars would be terrible on phones and tablets since they'd need to be always visible, and big enough to be tappable, and would waste collosal screen space; but some people would prefer that. The UI would need to have a permanent banner that explicitly labels the UI context, essentially a "permanent tutorial mode" that explains computing abstractions, for example with a banner that says "YOU ARE CURRENTLY VIEWING RECENT NOTIFICATIONS. [GO BACK]" (otherwise, you get inadvertent swipes, and "hey, where'd my video go!"). Designing "one UI for everybody" is hopeless. This is an obvious accessibility issue; and I don't understand why no company is building optional "tutorial modes" into their UIs since I'd assume the amount of people struggling with computers is a lot higher than the amount of blind or paralyzed people.
