As a counterpoint... 50 or 60 years ago your average person wouldn't be familiar with QWERTY unless they were in one of a fairly small number of professions (secretary, author, journalist...). QWERTY was something you had to learn.
These days everyone types on a keyboard. It's way more universal, to the point where a non QWERTY layout has to impose additional cognitive load.

It was common to type on a keyboard also before, it just was a typewriter's keyboard.
