But if you adjust the bets for the utility, then, if you're a perfect utilitarian, you should chose the highest expectancy, regardless of the risk involved. Between being sure of getting 10 utilons and having a 0.1 chance of getting 101 utilons (and 0.9 chance to get nothing), you should chose to take the bet. Or you're not rational, says dvasya.

It's not "or you're not rational." It's "or you haven't measured your utility function correctly." If you don't pick the option with higher expected utility, it's not actually utility.

We have a limited power for making computation. The first problem of taking a risk is that it'll make all further computations much harder.

So put that in your utility function. The certainty effect is not always a bias.

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 have the exact opposite view. I liked A Fire Upon the Deep and felt that Deepness had a woefully anthropomorphic and unimaginative alien world, cartoonish cast and a plot that drags on.

Aside from these two I've read Marooned in Realtime and True Names, and both were quite good. Overall I'd label Vinge a decent, albeit clearly second rate writer.

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.
