When The Vacuums Came For Me

Nightmare Number Three - Stephen Vincent Benet

We had expected everything but revolt
And I kind of wonder myself when they started thinking--
But there’s no dice in that now...

For a while, I thought
That window-cleaner would make it, and keep me company.
But they got him with his own hoist at the sixteenth floor
And dragged him in, with a squeal.
You see, they coöperate. Well, we taught them that
And it’s fair enough, I suppose. You see, we built them.

Definitely RTWT.  (H/T to Jerry Pournelle.)
