I can't parse this. Are you saying it's tautological? Or something else?

Let me rephrase: a lot of things in utility theory stop making sense if you stop looking at utility as a function to be maximized.

In a way that is not "as a function to be maximized."

Ok, here are the possible interpretations: Utility is not something that society maximizes. Utility is a psychological construct, akin to happiness, that humans sometimes try to get more of but not always. Humans are bounded agents and can't maximize for that reason Etc

None of the above. The interpretation is ConstructedWithMaximizationInMind, a long German word.

How is utility different from loss function? The latter is ConstructedWithMinimizationInMind. It is difficult to look at loss function in ML in any other way -- that construction is its defining characteristic.

Well utility theory goes through the trouble to derive utility functions from ordinal preferences. But I'm not sure I get your point with this comparison

Both are supposed to represent how valuable different outcomes are to a decision maker. If that representation is accurate, maximization/minimization is implied from the decision maker's perspective.

Of course no real life agent has a single consistent set of preferences, or can literally optimize (which takes boundless resources), etc. So even if you get that function right, it may not be useful to describe their behavior. But it can often be a good approximation.

Anyway, getting late for this potat. G'night.
