Debates over pornography or political extremism on the Internet are similar in many respects to the continuing controversies over censorship of books, magazines, motion pictures and television programs. An example of the resistance to change comes from Saudi Arabia. In 1994, Saudi Arabia took steps to ban satellite television dishes. It is seeking to defend religious and social mores. A cabinet decree, carried by the Saudi Press Agency, banned the use, import or manufacture of satellite dishes, microwaves or any parts of either one in Saudi Arabia.
Futurists are people engaged in an organized study of the future.
Social predictions can be made, in part, by assessing the social impact of technological and scientific changes. For example, in 1783 passengers traveled by stagecoach at six miles per hour. In 1883 they traveled on steam-powered railway trains at sixty miles per hour. Today, more than twenty million people travel routinely by plane at six hundred miles per hour. Physicist and futurist Gerald O'Neill has estimated that in another one hundred years, the typical passenger speed will be six thousand miles per hour.
