Try to teach someone who doesn’t work with computers how much a computer might make their job easier. The most common reaction you find is stark reluctance. Why would anyone be against earning something that might make their job easier? Often it is because they fear that something that makes their job easier might one day take over their job.
Teaching is like asking someone to go on a trip. Just as no one is going to take you up on an invitation to travel on a trip from which they would never return, people will be reluctant to participate in learning about their own obsolescence.
When you try to teach anyone something new, you have to make it clear from the outset that the destination is someplace we’d all like to go.
