Of course, heroin and candy bars aren't exactly civilization-level risks - they're regulated to various degrees, and the people that overconsume simply self-select out of existence. I'm skeptical that an entire society would fall under the spell of a game (even a really good one) before society develops protections against it (through regulation and cultural norms).
Excellent article about superstimuli here: http://lesswrong.com/lw/h3/superstimuli_and_the_collapse_of_...
Of course, I suppose I might see things differently if a blood clot turned half of my brain off for a while.
If a decision tree (or a clever algorithm or whatever) REALLY did perfectly mimic a thinking human (including our ability to learn), do you still think it wouldn't REALLY be intelligent? That there's some sort of important, qualitative difference between being shifted through a decision tree and sensory inputs and feedback loops building up neuron action potentials? That may be true, but the evidence is heavily stacked against such a worldview.
That said, I agree that this is a bad approach to AI. It's not like people haven't been trying to stitch together various subproblems of intelligence for the better part of 50 years.
This. As far as I can tell, "complexity science" is really just a dumping ground for things we haven't figured out yet. Some pattern seemingly ‘emerges’ out of nowhere? Complexity! Feedback loops causing unpredictable behavior? Complexity! Non-linear or ‘chaotic’ behavior that's difficult to interpret? Complexity! Don’t know where something starts or stops? Complexity! Self-reference or deep, recursive hierarchies doing something weird? Complexity! You can’t talk about any of them without using the phrase “don’t know”. It’s a field defined by our ignorance.
"Mr Coolidge's genius for inactivity is developed to a very high point. It is not an indolent inactivity. It is a grim, determined, alert inactivity, which keeps Mr Coolidge occupied constantly" - Columnist Walter Lippmann, 1926
I'd also suggest moving the google ads to the far right of the page. They were the first thing I saw and I was immediately annoyed by them.
As far as the content goes, you need a lot more explanation as to what sort of analysis you're actually doing, and what the graphs mean. Many of your graphs and charts are extremely cryptic, and they're frequently put at the end of the post with nothing following them.
Furthermore, you've got the unfortunate combination of writing in a stilted, scientific style (which really, you should never do) with posts that really don't have much scientific content to them.
Overall I'd say you need to focus more on your actual writing and less on everything else.
It's encouraging that Robin Hanson (who's a former physicist) has called the book excellent: http://www.overcomingbias.com/2010/01/from-eternity-to-here....
From his description, and from the bits and pieces I've picked up on other blogs, while the book is a popular science book, it's skewed much more to the science side than the popular side.

I have an extremely similar problem, where I feel like I always have to be right about...well, whatever I happen to be talking about. Because big personality changes are hard, instead I try to control some specific behaviors that get me into trouble, such as getting defensive and trying to sound like I know more than I do. That may be a better goal than a complete personality makeover.
[If you're interested, I wrote about getting defensive here: http://www.hegemonicon.com/blog/?p=184 and sounding like I know more than I do here: http://www.hegemonicon.com/blog/?p=683]
I'm equally perplexed by his overall point of "genetics is complicated, therefore genetic engineering and capitalism is immoral."
Insurgencies operate by leveraging small-scale, decentralized groups against a large, slow-moving beaurocracy. They succeed by operating faster than the beaurocracy (inside their OODA loops), leveraging the environment to their advantage and attacking critical points of failure. They're difficult to fight against because of their speed and the fact that they don't readily present targets to be attacked.
Granted, the Civil rights movement was largely grass-roots, but it's not clear to me why a comparison to an insurgency is apt.
"Mathematics is the minimal environment to preserve ideas."
They apparently tried to pull something similar with Peter Jackson and the billions of dollars from LOTR, though Jackson did end up taking them to court.
2) That 400 tons is not going to scale up with volume. Density of lead is around 650 lbs/ft3. Let's say you have a big ship, a mile in diameter. And let's be generous and put a 4 ft shell of lead around the whole thing. 4/3pi(5280^2-5286^2) * 650 * 1/2000 = 57000 tons of lead = 52000 metric tons. A drop in the bucket, tiny compared to the amount of steel and other material that would make up the rest of the structure. (Annual steel production is around 100 times more than of lead. We won't be running out of it either.)
The bottom line is that unless you're talking about transuranics or other extremely rare elements, or are building things at comically large scales (ie: thousands of ships) amount of construction material is not going to be a limiting factor in starship design.
