Is risk aversion really irrational ?
Faber20

If you don't pick the option with higher expected utility, it's not actually utility.

The point is that we may have utility functions where u(p1A+p2B) != p1u(A)+p2u(B). That is, the utility of a bet may not be equal to the expected value of the utility of the outcomes.

I am well aware. That's only the case for linear, i.e. 'risk neutral', utility functions. The thing is, utility is defined as the thing you are risk neutral with respect to. If you're not risk neutral with respect to it, then it's not utility.

One of the points in Deepness is that we almost exclusively experience the aliens as translated by the human "translators": due to their extreme skills, they are able to make the non-human easy for the humans to relate to.

In a brief glimpse near the end of the story, Vinge gives us a hint that perhaps the aliens aren't as human-like as the "translators" has made them seem.
