Isn’t it good that it spins up without no way of stopping it? Why would it be a problem that we do have a way of stopping it?
I frequently make this error when I talk. My brain thinks of different ways to phrase what I want to say, but when I speak it starts with one and finishes with another. The result is almost always wrong in the way the title is, ie some variant of a double negation.
Sometimes it happens when I type, though I try to read it multiple times so often catch it.
