Or perhaps less insidiously, a lot of answers are out of date. I remember that when I did AI game programming, I wanted to build a behavior tree, so in a recent project I Google for that. I get tons of great resources for behavior trees, libraries, examples, etc.

Except there's a lot more on the cutting edge I should be considering. Maybe GOAP is the right fit. Maybe HTN. Maybe something else. Sometimes these searches turn up results that are too specific to the old way of doing things and don't lead me to the latest and greatest.
