Look at the original scroll bars, they do quadruple duty: they tell you how long the document is, where you are in the document, let you jump to the area of the document you want, and let you scroll slowly. Modern scrollbars are a tiny strip that you have to keep poking at to make them visible; how is anyone going to learn to use that unless they already know about them?
So many products have a short lifespan now, apps and websites, that it's not worth the time making them amazing. Anything good required someone to improve it over and over. I save links of cool projects I see on Hacker News and half of them stop working after a year. Almost none of them have their full original functionality after 5 years, and are full of broken links, crashing backends, and incompatibilities.
It would certainly lessen the incentive to switch apps if it was difficult to learn the one you know.
It's recognition over recollection.
It is well known that recognition is easier, and that's why consistency help so much.
But used everywhere, as if it was the only available tool, it makes discoverability less safe, hence it reduces it.
If street signs are well positioned I don't need to know the route, if there are no signs and I don't recognize the place, I'm doomed.
If an app does one thing, it's easy to remember how to do that one thing.
But if another app does the same thing in a different way, now I have to remember two things and recall from memory which one uses which way.
I used to think that UX inertia was a quality for old people not comfortable with computers. I thought that a younger generation which grew up using computers would be more comfortable and not show the same monkey-see-monkey-do habits. I was wrong. I watched a teenager consistently prefer to delete by right-clicking and selecting "Cut" instead of pressing the delete key, even though he knew it was the same thing and would occasionally use the keyboard. But because the "Cut" command was the first thing he learned that made an item disappear that's what he does. This application has different actions if you drag with left-click or right-click; he frequently confuses them. He didn't know that you can select multiple items by holding down the shift key. This is an honors student who has been using computers his whole life.
Other than students pursuing a computer career, this is the typical teenage computer user. It's not that the UI is too difficult or opaque. They simply don't care to learn more than a surface level understanding.
The objective isn't to create a world of gurus. It's to improve quality of life for everyone. I'd certainly appreciate a computer that allows me to geek out to my hearts content, but I am not the target audience. And the thing about a well designed simplified interface is it's simpler and more efficient for everyone, including the gurus. The catch is a lot of simplified interfaces aren't so well designed.
A lot of what he says resonates with me. Except the bit about computers needing to be difficult to encourage learning. That's the adversity-builds-character mindset that I disagree with. The computer I learned to hack on was a Macintosh IIsi. It wasn't bare metal like a 8-bit computer that booted into BASIC. Nor finicky with lots of arcane configurations like a Windows 3.1 machine (and I've used both of those as well). It had all the it just works plug-and-play that he laments in Windows 7 but as a curious kid with a hacker mentality it served me just fine. Enough that by the time I graduated from it I was modifying the System with hooks written in 680x0 assembly.
But the author really goes wrong, I believe, in his conclusion that the cause of digital literacy is served by forcing users to be gurus. This is entirely wrong and is the crux of the observation I made above. There is a myth in UX development that programmers are targeting a conceptual user that exists somewhere on a continuous slope between novice and power user. The article ends with suggesting that computers be taught by setting people onto this theoretical path. (And to be honest I think he's mistaken that this isn't what we've already been doing and shown to not be effective.) But what if that path doesn't exist? Then trying to teach anyone that way will be fruitless.
My thought is that there is no gradual progression. Most people are not going to be able to learn computers the way that you and I have. So they need different ways of using computers than what we are used to. And that will mean a lot of disruptive ideas, which we may be suspicious of and call it "dumbing down". But what we should be more skeptical of is our own assumptions.
So if average people want to learn computers differently than nerds do, what we certainly don't want is to cut off the paths of discovery that lead to the next generation of super users, hackers, and developers. Both ways need to be preserved and encouraged to allow average users to get the most benefit of technology, while encouraging the more in-depth learning by those who want to be more deeply involved.
I find modern applications (especially mobile ones) much harder to discover and use. If you're a teen, you have plenty of time to experiment, but as an adult, I just want to get the work done.
Yeah, you could say that I don't want to learn.. but I just want to learn bare minimum to get the job done. The application itself doesn't have to be minimalistic.
