The Jam That Never Thawed

People love to say the QWERTY keyboard was built to slow typists down. Not quite — and the real story is stranger. It was arranged to stop a machine from jamming. On the earliest typewriters, the metal bars for neighbouring letters clashed and stuck if you struck common pairs too fast, so the layout deliberately flung frequent pairs far apart. The point was never slowness; it was keeping the hardware from tangling itself.

Then the problem evaporated. Better machines came, and then no machines at all — just glass screens with no bars to jam. But the layout never changed. Faster, saner arrangements were invented and proven, and almost nobody switched. Your fingers still obey the ghost of a nineteenth-century mechanical flaw, every single day, on a device that has no moving parts to protect.

It is a fossil you operate with both hands, fixed in place not because it's best but because everyone already learned it.

And if a dead machine's flaw can outlive the machine — what else are we doing for reasons that stopped existing?
