The QWERTY keyboard was designed in the 1870s to space out letters that were frequently used together, and so prevent jams at the ribbon. Now that keyboards are electronic, it would make more sense to lay the letters out in alphabetical order - making typing both easier to learn and quicker to perform. What keeps QWERTY in business? Inertia. Too many of us are used to the existing keyboards and can't easily retrain our fingers. As the great eighteenth-century philosopher and MP Edmund Burke used to argue, it is not enough to show that you are proposing something better; it must be better by a sufficient margin to justify the upheaval of getting there.
