Now they need a spare in case one quits working.
A few years ago I was working part time in an a gas station/convenience store. When power went out we weren't suppose to sell anything.
Some clerks would just hang the closed sign. Some of us sold stock and added 6% and made a list.
A few weeks ago I read they are thinking about not teaching cursive handwriting in schools.
Do you know what they should teach in school? Latin. And making kids learn how to text on smartphones like a competent being that has a proper grasp of the English language and not Bingo or Walmart. I don't speak Walmart, nor Bingo. I don't understand why ANYONE has to be forced in doing so.
The major problem is that ordinary users of PC's expect them to just work, like a kettle or a toaster or even a more than basic coffee maker. Along the way MS & Apple have make fundamental changes to where things used to be or how they should be configured, like printers or shared folders. Then, overnight a patch was applied that made something not work today like it did yesterday. That's when the ordinary user, who are just that, users, come unstuck because they have never explored because they aren't interested to explore, they just want it to work.
I've been saying for some time now that we are making PC's and servers etc far too complicated for the average user, somehow we need to simplify it.
The next big headache is the "cloud". People frequently lose data on the PC on their desks so I can't wait until users phone to say they want us to find what's happened to their data which could be on any one of a dozen "cloud" providers datacentres :-)
Personally I think the problem is not that people are stupid or can't learn, it's that they dont WANT to learn.
And not just about computers either. The number of public forums I frequent where people will submit posts littered with simple grammatical errors ("your" and "you're" / "there", "their" and "they're" anyone?) is astounding. And when someone pulls them up on it, they're accused of being a "grammar Nazi". Instead of asking which term would be correct, it's a case of "this is not a spelling forum".
The wider problem is that most forms of education are not exactly fun and engaging. That's not to say they can't be, just that educators often don't get reward for making it so or don't have the imagination to do so.
Part of the problem with computers, though, is that people don't understand fairly simple Operating System concepts (of which binary is not one) which ultimately makes them scared because they think they'll somehow break something. So they don't try anything different.
Yes, people don't want to learn about computers. But frankly, they shouldn't have to learn very much to use one effectively. Most technology these days requires that be able to figure it out to some extent. Try a new TV, or DVD player or TiVo or Cell Phone or even some new cars and what not. We all know people that can't set their digital clocks, or can't figure out how to program phone numbers into their 10 years old cordless phones.
But, the problem is that all those things.. TV's, phones, cars, whatever also have low-end versions that are basically just the simple part. Those exist in computers as well to some extent, such as a Chromebook. But, most people want computers to be able to do any possible thing they want to throw at it. And that means computers have to be more complex.
Technology requires a certain frame of mind. The frame of mind that says "Oh, this is new.. let's figure this out" rather than "Oh my god, it's something new, I can't figure this out".
Lots of people have that frame of mind for things they like. Music, Cars, Crafts, cabinet making, whatever.. but they just don't find enough interest in figuring out technology to make it worth it for them. But, they're more or less forced to use it, to keep in touch with friends and relatives, to apply for jobs, to get directions, etc...
Try one of those smart TVs. I have friends that have one since 6 months they still did not figure out how to properly record a program. And when you change the password of the router, they are completely lost. And these people are pretty smart.
I got a new car in November. What a disaster. It has 2 screens with a gezillion settings plus about 50 switches on the dash. The manual is 520 pages - even the manual for just the radio is 120 pages. And I don't even have a navigation system. For that I use my tablet.
This thing brakes when I get too close to a car ahead of me, a red light flashes when a car is driving next to me, the engine stops when I stop at a red light, resumes when I release the brakes. I am really not driving the car - the car is driving me. I think it will take me 3 years to figure that car out. I really miss my 13 year old previous car that had 3 instruments and 5 buttons.
But when you get yourself a computer then it's quite normal you will or at least try to gain some extra knowledge about it. It will be inevitable to remain "dumb" on the matter.
And ensuring others don't break your stuff by trying to fix it (you try to describe them the problem) then break it yourself and learn something in the process.
