Christopher Latham Sholes, the man who invented the first commercially viable typerwriter and sold it to the Remington Company, was born on February 14, 1819. Can you imagine the authority typewritten letters would have caused in the first few years?

Don't blame Mr. Sholes for the fact that typing a word like "plaque" or "apples" gives you more pinky exercise than a person needs in a week. The QWERTY design had two advantages. It prevented the jamming of keys, and it also allowed a ham-handed Remington salesman to pound out TYPEWRITER all from the top row. Mr. Sholes himself came up with an improved design to the finger-twisting QWERTY keyboard after a couple of years, but by then the Remington sales force had their patter and demo down. Nothing in the 130 years since Sholes patented his machine has dislodged Queen QWERTY.
Back to correspondence with authority. What can we do so our letters to donors jump out of the envelope instead of jumping into the trash can? One philanthropist told me that if I wanted her to read something, it needed to be in a hand-addressed envelope. Another said that, when she gets an invitation to an event, she scans the names on the host committee, and, if none of them are familiar, she throws it away. A donor who had made a fortune creating a bus tour company) claimed to have not seen a letter into which I had poured hours. I later learned he was dyslexic and could not read.
It all comes down to the need to know your donor. No gizmo, QWERTY or otherwise, is going to change that.
