6. Ethernet Inventor Predicts Internet Collapse
Quote: "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."
Founder of 3Com and inventor of Ethernet, Robert Metcalfe, made one of the most insane predictions ever when he said the Internet would crumble in one year. He even guaranteed to literally eat his own words if the bold prophecy failed to come to fruition. Living up to his promise, Metcalfe took his keynote speech during the International World Wide Web Conference in 1999, put a printed copy of his declaration into a blender, combined it with liquid, and drank it in front of the entire crowd. He could have just said he made a bad call.
