An old-fashioned typewriter works like this:
You press the key, if you don’t miss,
The typebar swings and hits a small head,
Compelling its owner to paint in dread.
A typewriter gnome has been taught one letter,
That it will remember (at least it’d better)
How to portray with some ink and a brush,
Always the same, no mistakes or mush.
The “TSAK” you hear, a head-on collision:
A new letter in your peripheral vision.
Therefore, computers are more humane,
No chance of contusion in a tiny gnome brain.
