• When trains were first developed, the King of Prussia confidently predicted: "No one will pay good money to get from Berlin to Potsdam in one hour when he can ride his horse there in one day for free."

• In 1903, the president of Michigan Savings Bank gave this market advice to Horace Rackham, Henry Ford's lawyer: "The horse is here to stay. The automobile is only a fad, a novelty."

• A British parliamentary committee assessed whether Edison's light bulb would ever be useful. They concluded it was "unworthy of the attention of practical or scientific men."
