In 1900 the Ladies Home Journal made 29 predictions about the year 2000. Sample:
There will be air-ships, but they will not successfully compete with surface cars and water vessels for passenger or freight traffic. They will be maintained as deadly war-vessels by all military nations. Some will transport men and goods. Others will be used by scientists making observations at great heights above the earth.
These prophecies reveal as much about the nature of science fiction as about the nature of science. They’re often utopian, or naive extrapolations of existing knowledge. And change is accelerating. I’m sure the world of 2100 is literally unimaginable to us today. It’s not even worth trying.
