There are still people today who cannot read, for sure they exist and live at a severe handicap. There are also people today who are technophobic, shun computers, don't use computers and believe they can get by without having to learn to use them. They will limit their ability to earn money, to learn, to obtain employment, or to succeed in a myriad of other activities.
Some people fear marriage, it's an unknown.
Others fear the ocean another unknown, some fear flying. But none of these things need be fearful in and of themselves. The computer should be less fearful today than at any previous time in history. Because there is more help, more training, more books available. The software and hardware that runs on these machines is getting better, less expensive and easier to use.
