Ooh, tingly. Welcome to Cnet Top Five, where each time we meet we count down another hot Cnet list, I'm Tom Merritt.

According to science fiction, the future is a wondrous place. It’s a land drench with technology, where everyone donned their leotards. Boards a PanAm flight to the moon. And mingles with a lizard or insect like aliens. And all the restaurants are Taco Bell. Science fiction is not so good with predictions. So, let's count down the top five worst sci-fi predictions.

At number five, atom powered everything. As soon as humanity invented all that destructive power, we figured we harnessed it in no time. And have atom powered cars, atomic trains, even atomic washing machines. But we do have atomic power, it’s just not so portable.

Coming in at number four, killer/household robots. Sci-Fi can't really decide if everyone will have a friendly robot pal in their home or those pals will turn on us and try to kill us all. But we’re all supposed to have robots by now, either serving us or chasing us.

Up to number three, a moon base. When Apollo 11 put man on the moon in 1969, they figured it wouldn’t be long before there was a moon hotel and moon casinos and whole moon cities under little glass bubbles. At the very least, we should have got moon mines. Nothing. They haven’t even back to the moon since 1972.

Sliding in at number two, jet packs. Where are our jet packs science fiction? Oh sure, we see them at the super bowl or the Olympics opening ceremonies, but I want the personal jet pack that lets me cut down my commute. You promised.

Before we get to number one, time for another lame prize question. One sci-fi prediction that hasn’t come true is the zombie invasion. But the University of Ottawa recently did a study of what would happen in a zombie invasion. How long did they say it would take for zombies to conquer an average city?

Alright, let's get to our number one, the worst prediction of science fiction. The future we were promised that was all a lie. At number one, its flying cars. Okay, Mauler fans, I know they exist, technically. But where are they? I can't ride to work in one. I can't dump my son down a pneumatic tube from one. I can't even find a dealer near me. Over and over again, science fiction has bet on the flying car and over and over again science fiction looses. Some day? Maybe. My guess is all restaurants will become Taco Bell before that happens.

Well that’s it for this edition of Cnet Top Five. Don’t forget, answer our lame prize question for the chance to win the decidedly not lame pack of zombies. I'm Tom Merritt. See you next time.
