Make money fast!
Well, 50 years ago we were promised robots, flying cars, cheap and reliable space travel, etc.
Whenever I see this kind of gullibility in the media I think of ways to make money on that. One that comes to mind is to open an "International University of Futurology" where pseudo-boffin wannabees could defend their PhDs in wildly guessed, utterly unprovable and inane themes, like:
* In 2030 television will be broadcasted directly into your brain.
* In 2090 nanobots will be able to cure any kind of health problems, and will be delivered nasally throught scratch-and-sniff interfaces in your own computer monitor (making life easier for spammers, too).
* In 2210 sex organs will be plug-and-play, you will be able to change them as you like.
* In 2300 most of mankind will be rendered so stupid due to lack of common sense, sloppy education and media influence that they will be unable to distinguish between fact and fiction.
Wait, change the date on that last one.
