Yes, but that moral is attached to a story. Morals and saws work as handles - they're useful for communication if both you and your interlocutor know the thing they're pointing to. Conversely, they are of little use until you read the story from which the moral comes, or personally experience the thing the saw talks about.

Eliezer Yudkowsky tells a long story about an Outcome Pump. Aesop tells a short story about an eagle and a tortoise. The point made is the same, as far as I can see.

[TeMPOraL]

Eliezer tells the story that elaborates on why you should be careful what you wish for. Of about a dozen versions of the Eagle and Tortoise story I've just skim-read, none of them really has this as a moral - in each of them, either the Eagle or a Tortoise was an asshole and/or liar and/or lying asshole, so the more valid moral would be, "don't deal with dangerous people" and/or "don't be an asshole" and/or "don't be an asshole to people who have power to hurt you".
