Why should the keyboard be standardized to the current "QWERTY" keyboard key layout? This is because at first, the keyboards of typewriters were arranged in alphabetical order, and typewriters were all-mechanical typing tools. So if the typing speed is too fast, some key combinations are easy to get stuck, so Christopher? Larson? Shoals invented the QWERTY keyboard layout. He put the most commonly used letters in the opposite direction, and slowed down the typing speed as much as possible to avoid getting stuck. Shoals applied for a patent in 1868, and the first commercial typewriter with this layout was successfully put on the market in 1873. This is why there is today's keyboard arrangement.
The existing computer keyboard layout follows the design of mechanical typewriter, which is relatively old and not necessarily the best design. However, because it has been used for a long time, habit becomes nature, and no one wants to learn a new keyboard layout again in order to adopt a more scientific design.
