I have to disagree here. Having different rules for the AI would make the game not understandable and overly complex. "Cheating" is in no way an acceptable path to patch an incapable AI. But on the other hand, saving / loading is not acceptable either, I never do that, this is plain cheating too.
To me, a strategy game needs to have plain and clear rules, and all players abide by those same rules. I cannot imagine enjoying a game where one team plays soccer (no hands allowed) against another team playing rugby. A plain mess if you ask me.
AI could be improved. The devs are showing us that by simply doing the opposite: every new patch seems to make it worse, either because the newly introduced mechanics are clearly disregarded, either with apparent typos (see the "AI crazy about science" thread), and insufficient playtesting.
@Infixo is apparently having some success in improving things with what is made available to modders, so it is possible. Deciding on your goals and pursuing a victory in a consistent way seems to be a key requirement that the AI is not doing, for instance.
