>Every engineering decision has costs as well as benefits. This is only true if you are superstitious or religious and believe that good things that happens to you (or humanity in general) must be balanced out by something bad happening.

Are fucking serious? Have you built anything significant? This is a very empirical view, not a superstition. If you want to learn more about this, and aren't just trolling look at the development of the A4 Skyhawk, the lunar lander, the space shuttle ... hell, any well documented large system. I wish I could reach through the internet and smack you in the head for such a stupid comment.

That's such an irrational assertion, ironically enough. Every decision has a trade off, even non-engineering decisions. It's called opportunity cost.

I remember reading about the same thing in terms of algorithmic complexity (in the context of data compression), and how one can only shift entropy about. Anybody got any keywords handy for practical examples? My hour of searching ended with conservation of information and black holes...

  Opportunity cost doesn't make all decisions zero-sum. There is a quirk of human psychology that makes us believe that most things must be zero sum (i.e. that anything I do that improves something I care about must have a 'payback' at a later date and that to achieve a good outcome I must always make an equivalent sacrifice). JabavuAdams is falling for that. Although his inability to control his own violent emotional outbursts is probably going to be the more significant problem in his life.

Costs and benefits don't usually add up to 0. If they did, everything you do in your life would be absolutely irrelevant. The trick is to chose things with best cost+benefit value, and if it's not easy to express all costs and benefits in a single unit (because it may be hard to estimate them), then you chose so that you get costs and benefits you like the most.
