In the technology world, bold predictions abound, and they should. Placing big bets in one direction or another is how this industry works. Some pundits try to make educated guesses about where tech is headed, while others prognosticate in reaction to disruptive technologies that could boost (or threaten) their business.

As we all know, foretelling what’s going to happen in 5, 10 or 30 years is pretty much impossible, but some predictions are so spectacularly wrong that they should be immortalized. That’s why I’ve selected these gems from some of the biggest names, publications and research firms to present the 10 worst tech predictions of all time. A couple of these timelines haven’t yet passed, but I feel comfortable predicting them as total fails now.
