I asked a girl out on a date. She said she'd be wearing _bell_s on the
expected night but couldn't be sure if she'd be able to make it
because her decision was dependent on how well her _curve_s were
feeling/looking in front of the mirror that night.
That's the nature of the...
or is this view misguided?

Like one of the articles said though, maybe we all have our own bell
curves in relation to enhancement and how much is ever too much to the
point where it starts compromising some things. I think its the same
for medication, in that some people just require less/more than others
due to body size, physiological function or brain chemistry.
In the case where some argue that unlimited processing capacity &
storage is a negative thing, maybe this only holds true when the
scenario doesn't involve having this 'ability' matched by other
compatible criteria. Along the same vein (although, like many things,
I guess its still a misunderstood concept), having lower than average
latent inhibition and the positives/negatives associated with it
portrays a similar notion, where if low latent inhibition is coupled
with low levels of intelligence it can be cognitively disastrous,
however if it is coupled with high levels of intelligence, more
positive outcomes, such as creative achievement, may result.
If anyone would like to add anything...

It's a little more complex than that - the 'curves' are defined by optimizing for multiple things simultaneously by our bodies-brains as designed by evolution. But humans are adaptation-executers, not fitness-maximizers, as the evopsych quote goes. And then you have the issue that many of the curves are not inherent bio-chemical trade-offs, if you will, but adaptations for old environments, which leads to loopholes - http://www.gwern.net/Drug%20heuristics
(The annoying thing is that Bostrom's paper, to a large extent, obviates that paper. But it was still useful for some examples. Oh well.)
