> Purposes are deduced from behavior, not from rhetoric or stated goals.
A light rewrite of the slogan "the purpose of a system is what it does".
I hate that slogan. It's supposed to be profound, but it's actually really, really dumb.
The whole point of the word purpose - its purpose if you will - is to be able to talk about the difference between what a system does and what it ought to do. To say the purpose of a thing is what it does, is to render the word completely redundant.
If the stated goals of a system don't match what it does, then either you have a dysfunctional system that needs to be fixed, or those stated goals are lies.
In these days of AI, it's all the more important to think clearly about purpose. Just because a system does a thing, there's not necessarily anyone who wants that thing. And there's definitively not any "spirit of the corporation" or "spirit of the nation" or "spirit of the language model" which wants it. Only persons want things.
