Literally the only use I’ve found for it that’s better than any other alternative is describing a thing to it that you can’t remember the name of. It’s usually right, and when it’s wrong you were probably never gonna find the thing on your own anyway.
But I don’t go to it first, only when I can’t figure out how to find the name any other way.
Logically, yes. But humans aren’t purely logical. They’re gonna have sex without access to birth control, even if they don’t want a kid. Not all of them, but a lot of them. So why not just let them have both control?
