Smithsonian magazine celebrates its 40th anniversary by writing about “40 things you need to know about the next 40 years.”

Out of the 40 predictions, some of the ones that intrigued me:

4. New cars will be given away, free.

11. The heartland will rise again.

12. The top US social problem? Upward mobility.

13. By 2050, one out of three US kids will be Latino.

25. Artists will run the world.

27. Everyone will make his own music.

36. Good-bye stereo; hello, hyper-real acoustics

40. Reading will become an athletic activity
