Unfortunately, this trend to more and more ubiquity can be detrimental. It's similar to other technology "advancements", and what they led to. Two obvious examples:
1. The calculator. I used to teach Mathematics courses on a part-time basis at various colleges, and the reliance by students on calculators kept getting worse and worse. It got to the point where students could not figure out the following simple problem without a calculator:
"If a shirt normally sells for $20, and there is a 10% off sale, excluding taxes, what will the shirt cost?"
It was amazing to see how deficient students were in trying to do such a simple problem without a calculator! And god forbid if it was slightly more complicated, with the problem being "If a shirt normally sells for $25, and there is a 10% off sale, excluding taxes, what will the shirt cost?". Another example: I was helping a student with a problem, and it got to a point where it was necessary to compute 32 - 17. I asked the student what is that. She first said "20", and I said no. Then she said 13, and I said no. She then said 18, and I said no. So I asked her what is the issue? She said she uses her calculator for something like that!
I thought to myself that these are (potentially) the future leaders of our country! I remember a saying I heard: The best calculator is your brain. It never runs out of batteries. Definitely true.
I did, though, have one student who offered some hope. I said to the class, what do you do if you are trying to buy a car, and the salesman states a price. If you need to do some further calculations, what happens if your calculator has run out of battery power? One of my students did say that she would take out some paper and pencil to try and work it out. Unfortunately, such a person was definitely in the minority.
2. Facebook, Twitter, etc. All of these "services" have resulted in less and less human interaction. Really, really sad. I myself need such interactions, and thus avoid using such services. Might be old school, but that's fine with me.
By the way, in doing a google search of "ubiquity", one of the definitions is:
"the fact of appearing everywhere or of being very common."
"the ubiquity of mobile phones means you don't really need a watch"
Well, that business about the watch is another example. I like to do some gambling at casinos, and do not like to carry my cell phone inside (might lose it, plus most of the time can't get reception). Well, casinos do not have any clocks, so how would one know what time it is? Well, I still wear a watch, and that works well.
I understand that ubiquity for computers is coming, but I truly wonder what it will do.
