"The Locked Keys – Why we are stuck with the world's most inefficient keyboard" explains the economic concept of "Path Dependence" through the story of the QWERTY layout. In the 1870s, Christopher Sholes designed the first typewriters. The problem was that if typists typed too fast, the mechanical hammers would jam. The solution? Create a layout intentionally designed to slow typists down by placing common letter pairs apart. Tech historian Arthur Key details how this "inefficient" temporary fix became the global standard. Even after technology advanced and jamming was no longer an issue (and better layouts like Dvorak were invented), the world couldn't switch because everyone had already learned QWERTY. "The Locked Keys" is a study in how history traps us. It illustrates that the best technology doesn't always win; sometimes, the first technology wins, locking civilization into a sub-optimal path for centuries simply because the cost of changing is too high.
