OMG, this changes my entire perception of everything I’ve ever known about my keyboard layout:
The first time I heard the lie, I was in fifth grade. Mr. Ward took me aside (or maybe he told the whole class, it was a long time ago) to tell me about the wonders of Dvorak, a different keyboard layout that was scientifically designed to be more efficient than the standard layout. That layout was called QWERTY, he explained, and it had been created to slow typists down. You see, in the olden days, mechanical typewriters could jammed if people hit the keys too quickly, so they had to put the common letters far apart from each other. The modern keyboard, I was told, was a holdover of the mechanical age.
