When it comes to predicting the future, sometimes tech aficionados get it wrong. Here's our round-up of the 7 worst tech predictions of the past 65 years.

Most predictions for the future are fairly vague. However, that doesn't cut it in the world of tech, where predicting the future is key to survival. But on occasions some tech aficionados have got it wrong. And in these seven cases, very very wrong.

So here's our round-up of the seven most foolish predictions the past 65 years of the tech industry. Read on to see just how wrong they got it. Then take a look at our Tech Predictions for 2009 feature, where real life psychics predict what might happen in 2009.

Foolish tech prediction 1

"I think there is a world market for maybe five computers." - Thomas Watson, president of IBM, 1943.

At the dawn of the computer industry, nobody really knew where this new technology would take us. But the explosion of desktop computing that put a PC in nearly every home within 50 years seems to have eluded the imagination of most mid-century futurists.

After all, when IBM's Thomas Watson said 'computer', he meant ‘vacuum-tube-powered adding machine that's as big as a house'. It's fair to say that few people ever wanted one of those, regardless of the size of their desk.

Foolish tech prediction 2

"Television won't be able to hold on to any market it captures after the first six months. People will soon get tired of staring at a plywood box every night." - Darryl Zanuck, executive at 20th Century Fox, 1946.

By 1946, movie executive Darryl Zanuck had already cemented his place in entertainment history as the producer of more than 100 films for the big silver screen. So who could have blamed him for underestimating the power of the small blue screen? I'm guessing that if Zanuck were alive today, he'd find himself just as mesmerised as the rest of us by the mind-crushing distortion loop that modern TV programming has become.

When it comes to predicting the future, sometimes tech aficionados get it wrong. Here's our round-up of the 7 worst tech predictions of the past 65 years.

Foolish tech prediction 3

"Nuclear-powered vacuum cleaners will probably be a reality within 10 years." - Alex Lewyt, president of Lewyt vacuum company, 1955.

In the 1950s, the only thing more certain than the red menace was the inevitability of atomic power. So when US-based vacuum cleaner honcho Alex Lewyt heralded a tomorrow in which nuclear-powered appliances would suck up dirt in every household, the news probably caused few eyebrows to rise. Remember, this was the era of radium-impregnated paint for glow-in-the-dark dials. Peaceful radioactivity seemed as safe as asbestos.

Of course, Lewyt's vision has yet to come true, and it likely won't until well after nuclear reactors are enlisted to power terminator robots.

Foolish tech prediction 4

"There is no reason anyone would want a computer in their home." - Ken Olsen, founder of Digital Equipment Corporation, 1977.

Digital Equipment Corporation was acquired by Compaq more than a decade ago, but in the 1970s, the company was a major force in the world of computing. Apologists argue that DEC president Ken Olsen made this quip before the advent of the PC as we know it, but ready-made personal computers such as the MITS Altair had hit the market a couple of years earlier.

And within four years of Olsen's remark, the release of the IBM PC had enshrined this prediction in the high-tech hall of shame.

Foolish tech prediction 5

"Almost all of the many predictions now being made about 1996 hinge on the internet's continuing exponential growth. But I predict the internet will soon go spectacularly supernova and in 1996 catastrophically collapse." - Robert Metcalfe, founder of 3Com, 1995.

In addition to being a legendary tech visionary and the man widely credited with having invented Ethernet, Bob Metcalfe was also a columnist for PC Advisor's sister title InfoWorld. And it was in that column that Metcalfe made what must have been the most regrettable comment of his career; indeed, he even promised to eat his words if his augury turned out to be wrong.

To his credit, Metcalfe made good on that promise in 1999 during his keynote speech at the International World Wide Web Conference, where he blended up a copy of his printed column with some liquid and drank it down before a crowd of onlookers.

When it comes to predicting the future, sometimes tech aficionados get it wrong. Here's our round-up of the 7 worst tech predictions of the past 65 years.

Foolish tech prediction 6

"Apple is already dead." - Nathan Myhrvold, former Microsoft CTO, 1997.

To be fair, just about everyone in the computer business thought that Apple was in its death throes when Microsoft CTO Nathan Myhrvold made this comment back in 1997.

Who could have predicted that, a little more than a decade later, that same company would be steadily increasing its share of the PC market while utterly dominating the digital music business and rapidly overtaking the field in the smart phone market?

Foolish tech prediction 7

Two years from now, spam will be solved." - Bill Gates, founder of Microsoft, 2004.

By recent estimates, the amount of spam currently glutting up the net is somewhere around 92 percent of all email messages worldwide. (And it won't do to claim that what he really said was "Two years from now, Spam [the sandwich filling] will be dissolved" - because the sculptable meat product remains as semisolid as ever.)

So, uh, good guess, Bill. Glad that's been taken care of.
