Utilities (in humans) are real numbers ranging from 0 to 1,000 that take action potentials per second as their natural units.

I downvoted the post based off this quote. To the extent that utilities are referring to the kind of thing that we describe with that term on lesswrong utilities are not anywhere near as simple as that. In fact things that we ascribe negative utility to can be significantly positive on that kind of encoding. Nevermind that the sience is out of date.
