39. structure vs style for AI

41. What are the style DOFs for AI? Can code be a style DOF? Does behavior mean code? Note: this is still code!

42. Where does the code live? Not in the DOFs

43. Code is not... intuitive expressive frugal blendable efficient intuitive expressive frugal blendable efficient tick_ai() is not a good DOF!

44. My Prediction... There will be a structure vs style decomposition for AI. There will be a structure vs style decomposition for AI. Its style will not be based on code. There will be a Photoshop of AI.

45. Near Term Look for the structure vs style DOF decomposition for your games AI. Look for the structure vs style DOF decomposition for your games AI.
